In the current post I try to explain what appears to be a paradox: given identical data, different schools of statistics disagree about the appropriate conclusion. Traditionally, there are two ways to interpret Probability: 1. Probability is the...

This post will be dedicated yet again to some experimentation with text analysis. I will be using mostly basic and classic NLP tools like word counting and DFM’s (Document-Feature matrix). I hope that in the next NLP post I will be using some mor...
