【Question】

Predictive Analytics: What tools do you use for Data Preparation, primarily for outlier detection and removal, Feature Selection etc. If you use R software, what packages do you use?

【Answer】

esProc is a great tool for data preparation. It boasts a rich variety of functions for structured data manipulation. It handles table joins or outputs a huge volume of data in an easy and convenient way. See Offline Dynamic Computation to learn more about esProc.

However, R language is a blunt tool for handling structured data. It is slow and has a bad support for big data handling.
