The Ultimate Guide for Choosing Algorithms for Predictive Modeling

There are three ways to look at data. The first is analytics. This is when you look at data from the (potentially very recent) past. Think analytics.

I am using R for building a predictive model. My data is stored in mongoDB collections. So i connected to MOngoDB using R to get the data and creating a dataframe in R by converting the BSON values to list and storing about 64567 records using a cursor, which took about 15 minutes.

Team Obama Mastered the Science of Mass Persuasion - and Won

Last October, a colleague and I speculated on how a special, powerful form of predictive analytics would revolutionize presidential campaigning—and, if successful, how it might be poorly received by the public thereafter. In our work, he and I focus more on financial, marketing, and online applications of this technology. But we bet the story would break within politics by 2016 or 2020.



Surprise: There's no wait! After Obama's win in November, we've learned they already did this.…

Setting up a cross-selling model

Cross selling campaigns aim at selling additional products to existing customers. 

A cross selling model estimates the propensity to uptake an add-on product for each scored customer.



A cross selling model can be built on the results of a test campaign to analyze respondents and identify customers with increased purchase potentials.



An easier approach which does not require the running of a test campaign, is to analyze the profile of customers who acquired the product of… Continue
