Why does Microsoft suck at data science?

Logistic regression is the mathematical theory of statistical inference, and the Python-based R code that implements it is one of the best tools for analyzing data in R. In this article, we’ll learn how to implement logistic-regression algorithms using Python, but also show you how to apply the techniques to other data science tasks, such as data mining, machine learning, or natural language processing.

By the end of this article you should have a working implementation of logistic regressions in Python, R, and Julia.
