I have this system of four nonlinear equations:
the unknowns are a1, a2, gamma1 and gamma 2. all other parameters are known. What I want is to plot the a1 vs sigma2 as below:
I tried findinstance but it takes a lot of time to find the results for any value of sigma2, Let alone plotting a1 for different values of sigma2!
Can anybody help me?
Thanks in advance
In a previous post, we noted that the majority of consumers who had a 7-year-old delinquency purged from their credit file saw improvements in their FICO® Scores. Now let’s look at whether these consumers’ credit-seeking behavior changed after the delinquency was purged and their score recovered. Were they more likely to apply for credit? Get approved and open new accounts?
To assess this, we looked at the proportion of the “delinquency purge” population (those that had a delinquency removed from their credit report between May 2016 and July 2016) that had a new inquiry or opened a new account in the three months following the purge window (August through October 2016).
In Figure 1, we compared those values to the same period a year earlier, to avoid capturing seasonal changes in credit habits.
The data showed that there was a minor increase in the percentage of consumers that had a new inquiry compared to a year prior, and a material increase in those that opened a new account. This is particularly noticeable for new bankcards.
For the “full recovery” population (those in the “delinquency purge” population who had no remaining serious delinquencies), the changes were slightly more pronounced, as seen in Figure 2.
We see a greater increase in both new inquiries and account openings for this segment than is observed in the broader “delinquency purge” population. Furthermore, we see higher rates of new account openings despite lower rates of inquiries than the “delinquency purge” population, suggesting a higher approval rate.
This supports the idea that these consumers, who have rebuilt their credit profile and FICO® Score through years of responsible behavior, are now very well-positioned to access new credit at more favorable terms than they would have been offered before (which in turn may induce them to take on new credit).
But perhaps the increase was due to other factors (such as less restrictive lending standards), and had nothing to do with the removed delinquencies. So we looked at the inquiry and new account activity for the “delinquency baseline” population (those who had a serious delinquency in 2009-2010 but did not have a delinquency removed between May 2016 and July 2016) as a benchmark for comparison.
In the “delinquency baseline” population, we found that there was actually a small decline in inquiries between 2015 and 2016, and relatively minor changes in new account openings. The figures look quite different from the increases in new credit activity seen in the “delinquency purge” population.
The difference in the year-over-year change in new inquiry rate between “delinquency purge” consumers and “delinquency baseline” consumers suggests an increase in the willingness of the “delinquency purge” population to seek credit, and increased confidence in their ability to get approved. And the data supports that confidence – the increase in new accounts opened is disproportionately large when compared to the increase in inquiries.
As we move further away from the Great Recession, consumers whose credit situation was adversely impacted but who have since righted the ship via responsible use of credit should continue to see marked improvements in their FICO® Score. Based on what we’ve observed from the “delinquency purge” population, their increased creditworthiness comes with expanded interest in and access to credit: a potential win-win for both lenders and consumers.

Many Chinese companies have risen on the back of mobile advertising, but a new report says fraud is rampant in the sector.
Global ad revenue wasted on fraudulent traffic could reach $ 16.4 billion in 2017, according to information from AppLift China. AppLift conducted a twelve-week study and found out that certain app categories are more susceptible to fraud than others, with entertainment apps and news apps seeing the most fraud traffic.
Mobile app categories with the most fraudulent activity include entertainment, news, and education with 22%, 22% and 21%, respectively. Meanwhile the apps with the least fraudulent activity dealt with parenting and shopping with 2% and 3%, respectively. More complex and sophisticated types of fraud have evolved such as click injection and click stuffing.
“As a leader in the mobile ad space, we firmly believe it is our responsibility to not only focus our efforts on detecting and fighting ad fraud, but to also share our learnings with industry peers so that we can all better understand the risks and fight fraud together,” said Tim Koschella, CEO of AppLift.
Web API is a new platform feature of Dynamics CRM 2016 that exposes CRM data over OData (Open Data Protocol). Web API offers REST based endpoint which can be used across a wide variety of programming languages, platforms, and devices.
Since Web API is intended to replace existing SOAP base endpoint I started using the Web API feature in JavaScript web resources to query for data.
Here are some queries which I found useful:
When using the Entity Name as it is the result will be an error “Resource not found for the segment”.
GET http://testserver/testorg/api/data/v8.0/mag_consumersetup?$ select=mag_name&$ filter=contains(mag_name,’Test’)
{
“error”:{
“code”:””,”message”:”Resource not found for the segment ‘mag_consumersetup’.”,”innererror”:{
“message”:”Resource not found for the segment ‘mag_consumersetup’.”,”type”:”Microsoft.OData.Core.UriParser.ODataUnrecognizedPathException”,”stacktrace”:” at
…………
}
Using the plural name of the Entity by added ‘s’ to form mag_consumersetups resolves the issue.
GET http://testserver/testorg/api/data/v8.0/mag_consumersetups?$ select=mag_name&$ filter=contains(mag_name,’Test’)
{
“@odata.context”:”http://testserver/testorg/api/data/v8.0/$ metadata#mag_consumersetups(mag_name)”,”value”:[
{
“@odata.etag”:”W/\”1257828567\””,”mag_name”:”Test A”,”mag_consumersetupid”:”e0b6ae92-4230-e711-80bf-00155d048d78″
}
]
}
When querying for all field values of Entity records the error “Property ‘stageid’ is of an unrecognized EdmPropertyKind”.
GET http://testserver/testorg/api/data/v8.0/mag_consumersetup?filter=contains(mag_name,’Test’)
{
“error”:{
“code”:””,”message”:”Property ‘stageid’ is of an unrecognized EdmPropertyKind. Entity mag_onboardingrequest has duplicate navigation property names. All property names (Navigation and Structural property) must be unique in an Entity “,”innererror”:{
“message”:”Property ‘stageid’ is of an unrecognized EdmPropertyKind. Entity mag_onboardingrequest has duplicate navigation property names.

}
Query only the fields you need by specifying a select statement and field names
GET http://testserver/testorg/api/data/v8.0/mag_consumersetups?$ select=mag_name&$ filter=contains(mag_name,’Test’)
{
“@odata.context”:”http://testserver/testorg/api/data/v8.0/$ metadata#mag_consumersetups(mag_name)”,”value”:[
{
“@odata.etag”:”W/\”1257828567\””,”mag_name”:”Test A”,”mag_consumersetupid”:”e0b6ae92-4230-e711-80bf-00155d048d78″
}
]
}
POST http://testserver/testorg/api/data/v8.0/mag_TestMultipleOutput
{
“error”:{
“code”:””,”message”:”Resource not found for the segment ‘mag_TestMultipleOutput’.”,”innererror”:{
“message”:”Resource not found for the segment ‘new_TestMultipleOutput’.”,”type”:”Microsoft.OData.Core.UriParser.ODataUnrecognizedPathException”,”stacktrace”:” at

Workaround is to change the ContactOutput type from EntityReference to String and return a json string representing the contact record.
POST http://testserver/testorg/api/data/v8.0/mag_TestMultipleOutput
{
“@odata.context”:”http://testserver/testorg/api/data/v8.0/$ metadata#Microsoft.Dynamics.CRM.mag_TestMultipleOutputResponse”,”StringOutput”:”test”,”ContactOutput”:”{ \”contactid\” : \”FA2A2CA9-B0FC-E211-A2E0-00155D0C8359\” }”
}
Use JSON.Parse to convert response from a Json string into a response object then JSON.Parse the ContactOutput string to obtain the contacted.
The issues build into the out-of-box (OOB) CRM integration with SharePoint, are described in the post “Dynamics CRM integration with SharePoint- Can we do better“
In this post I will describe how Dynamics SharePoint Organizer (SPO) offers better integration between SharePoint and CRM.
Dynamics SPO trial version,
Email2SharePoint – Upload documents to SharePoint by emailing them to CRM Queue, which activates CRM plug-in, that uploads the files attached to the Email, and save them in SharePoint with the related metadata / columns retrieved from the Email ()
Add SPO functionality to CRM Entity – A better way to integrate entities with SharePoint document location, and how to save relevant metadata to the document, retrieved from the attributes (fields) of the CRM record. A functionality I am going to describe, in details, in this post.
The function of SharePoint Organizer (SPO) is as it sounds, a methodological and consistent way, to organize documents in SharePoint, so that they can be easily found, when they are needed. In a nutshell, use less folders and more relevant metadata retrieved from the attributes of the CRM record.
The SPO function is a simplified way to upload documents to SharePoint. The CRM user, while he /she is in the record form, can upload files from hard disk, from documents attached to Notes, and from documents attached to Emails, related to the record, which are Emails where the Regarding field is the record we upload from. SPO function is also more efficient and time saving function to upload files to SharePoint. It allows multi-selection of files to upload in one step, unlike similar function in CRM OOB, which requires an upload of one file at a time, and only from the hard disk. In other words, with CRM OOB, to upload a file attached to an Email, it firstly needs to be saved to hard disk and only then it can be uploaded to SharePoint.
CRM OOB defines the folders and folders names where documents will be saved in SharePoint. SharePoint user finds it difficult to find documents spread over many SharePoint folders and without metadata to support SharePoint search functionality.
SPO uploads document to configurable folders and with metadata based on the attributes of the entity. As an example, when configuring the integration of Invoice entity with a location in SharePoint, you can also select the attributes: Name, Total Amount, Customer, Due Date, and Email address of the related Contact, as metadata columns in SharePoint. You can then use this meaningful metadata for search and metadata navigation in SharePoint. Updating payment due date from CRM to SharePoint, can trigger a SharePoint workflow to follow up payment on due date.
While configuring SPO, you can enable / disable overwrite of existing document in SharePoint, as well as to delete or keep the original attachments after they are uploaded from Emails to SharePoint.
Two million blog posts are written every day. You can only imagine how many other content pieces are out there. This information overload makes it extremely tough for marketers to stand out. Sometimes, all it takes is one viral infographic or video, but most times, that isn’t the case. Rather than focusing on what content to publish, you should also be focusing on who delivers your content.
This is where employee advocacy comes in.
The idea is to simply get employees to share your content across their personal social networks ‒ to tap into their connections to help grow your reach, engagement, and conversions exponentially. While there’s no universal strategy for running an advocacy program, there are some things you can do to maximize its ROI. To get started, here are five key elements to include:
Above all, the content that you provide employee advocates should be of high quality. But what defines “quality content”?
Quality content can range from a 4,000-word eBook to a 1-minute video clip. It can take weeks to produce, or just a few hours. There’s no set criteria for creating quality content. However, you need to make sure that employees are sharing content that exceeds their audience’s expectations. Focus on content that is valuable yet super engaging.
Starting with the latter, you can make your content more engaging by:
Next, don’t settle for one type of content ‒ go for a variety of original and curated pieces. Original content includes eBooks, case studies, webinars, blog posts, etc., that your marketing team created. Curated content consists of valuable articles and resources from third-party websites that educate your audience in a less self-promotional way.
Moreover, creating content that is valuable boils down to matching your readers’ intent. Take advantage of employees’ ability to gain insights and opinions about their audience; then use this information to create content that they’ll be interested in. This will also empower your advocates by proving their impact in the program.
Now, more than ever, customers want you to connect with them on a real and personal level. Employee advocates add this element of personalization by putting faces to your brand. They create a human bridge between your company and customers.
Taking this element of personalization to the next level, you can increase engagement by getting employees to share content that’s relevant to their role in the company and to the particular audience. For example, consider your salespeople. What type of content do they enjoy sharing? What type of content is going to best resonate with their audience?
Generally, your salespeople are more likely to share thought-leadership pieces, industry-related reports, and articles from well-known publications, because these help to position them as knowledgeable and professional. On the other hand, content that’s technical in nature will be perceived as less relevant by your sales team ‒ and similarly, by their audience.
Another way to set your employee advocacy program for success is by fostering an environment of easy and effortless sharing. Whether advocates are attending a conference or sitting on the bus, it’s important to make it as simple as possible for them to share a large amount of content, no matter where they are.
By using a proper social advocacy platform, you can make tasks like sharing content an easy daily routine for employees. Rather than having to search for content on their own, employees who use an advocacy platform like Oktopost are guided on which content topics to post, when to post, and how to do so. Giving employees the necessary tools will get the ball rolling in your program and ensure that more content gets shared.
Employees are the most essential asset of your marketing initiatives. Failing to incentivize them will result in less content being shared. Research shows that 69% of employees would work harder if their efforts were better appreciated.
Having a well-planned incentive strategy makes a huge difference and can really boost the ROI of your program. For now, here are a few examples of strategies that companies implement:
The type of incentive strategy you choose will depend on the number of advocates you have, your company’s hierarchy, and the personas that make up your program. For example, advocates from sales are more likely to value monetary rewards, while marketers will most appreciate public recognition.
It’s easy to launch a program and then just hope for the best, but to make it a big success you must track and analyze its performance every step of the way. First, ask yourself what “success” looks like in your program. Is it the impact on reach? The increase in social chatter about your company? Or maybe the growth in the number of leads? By setting specific KPI’s, you can determine what’s working and what’s not. You can understand if your content needs improving, if you’re posting to the right channels, and if you’re reaching the right audience.
It’s important that you accurately tie these metrics to individual employee performance and to ROI. For the latter, you’ll need an advanced platform like Oktopost. Oktopost consolidates all of your social media marketing activities in one place for easy management and reporting.
In your advocacy program, Oktopost allows you to track everything from which prospects converted, to which employee brought in the conversion, to the type of content the employee posted. It also enables you to measure the metrics gathered by your advocacy program in the ecosystem of your other marketing initiatives. The more you measure and make adjustments, the more successful your program will be.
A winning employee advocacy program requires a lot more than giving employees content to share. Implement these five elements for a sustainable and fruitful program that can be tied to ROI, and help your employees spread the word about your brand.
First person account of what happened is discovered.
One of the witnesses to the blast was Frank Baker, a sailor in the Royal Navy, who wrote about the events of that day in his diary. He passed his journal on to his son Rex before his death in 1977. Rex put the diary away and only recently rediscovered it.
“The first thud shook the ship from stem to stern and the second one seemed to spin us all around, landing some [crew members] under the gun carriage and others flying in all directions all over the deck,” Baker wrote. Sailors 150 miles out to sea heard the blast. On land, people felt the jolt 300 miles away. The shock wave demolished almost everything within a half-mile. “Our first impression was that we were being attacked by submarines, and we all rushed for the upper deck, where we saw a veritable mountain of smoke of a yellowish hue and huge pieces of iron were flying all around us.”
Frank Baker’s diary entry is believed to be the only eyewitness account of the explosion recorded on that day. Read the rest of it at Smithsonian.
Chinese smartphone maker Xiaomi signed an agreement with Samsung Display for the supply of OLED screens, which will be used on Xiaomi’s flagship smartphones in 2018.
Samsung will supply 6.01-inch rigid OLED panels to Xiaomi. The first batch will be shipped in December 2017. About one million panels will be shipped in the first month and 2.2 million more will be shipped in the second month. Financial terms of the deal were not released.
Xiaomi originally planned to use LG’s 5.49-inch flexible OLED panels. Unfortunately, the two parties did not reach an agreement because of the operation delay of LG’s new factory.
Media reports reveal that LG’s new factory E5 is expected to start operation in August 2017, which is about three months later than its original plan. The reason for the delay is because LG is upgrading its panel resolution from full HD to QHD, with 2156×1440 pixels.
