More and more companies are mining data about their employees to predict how they’ll behave in the future

A few weeks ago it was revealed that Google and the CIA—two organizations whose job it is to know what’s going on in the present—are working together to learn what will happen in the future. Through their respective investment arms—Google Ventures and In-Q-Tel—the geeks and the spooks each took a stake in a little-known Cambridge, Mass., company called Recorded Future, which bills itself as “the world’s first temporal analytics engine.” By scanning websites, news stories, blogs and Twitter… Continue

Dear Liz: I'm going to owe nearly $40,000 in student loans when I graduate in the spring with an associate's degree in political science with paralegal studies as my major.

NEW YORK -- Have you been working to boost your credit score before trying to get a mortgage? It may not yield the payback you expect.



The mortgage loan interest rates offered to borrowers with stellar FICO scores aren't much lower than the rates offered to those with a middle-of-the-road 720 score these days.

Interesting article from Business Insider: Strategic Defaults Are Real, Growing, And Scary

In my last article, we examined the shadow inventory to determine how many distressed properties (not on MLS) were almost certain to be forced onto the market in the not-to-distant future.

Hidden Decision Trees - A Better Approach to Scoring

Hidden Decision Trees is a statistical and data mining methodology (just like logistic regression, SVM, neural networks or decision trees) to handle problems with large amounts of data, non-linearities and strongly correlated independent variables.
