Track 2: Social Data and Telecom 
Case Study: Major North American Telecom
Social Networking Data for Churn Analysis

A North American Telecom found that it had a window into social contacts – who has been calling whom on its network. This data proved to be predictive of churn. Using SQL, and GAM in R, we explored how to use this data to improve the identification of likely churners. We will present many dimensions of the lessons learned on this engagement.

Spam Analysis Akismet-WPStats-Blogging

Here is a brief dataset I out after one hour of cutting and pasting from WordPress.com’s creative data style formats. It shows spam,comments,traffic, and number of posts written monthly.

Clearly monthly traffic is directly related to number I write (suppose A + B* Posts)

But Spam is showing a discontinuous growth especially after a big month (in which Reddit helped)

Akismet had some missing historical values (which is curious)

So what can we do with this dataframe in R or any other statistical software.
