What is Logistic Regression?

This tutorial is on the basics of applying logistic regression, using a little bit of Python. It is also a continuation of the post "What is Linear Regression?", which can be found here. It is a little counterintuitive, but Logistic Regression is typically used as a classifier. In fact, Logistic Regression is one of the most used and well-known classification methods Data Scientists use. The idea behind this classification method is that the output will be between 0 and 1. Essentially returning the probability that the data you gave to the model, belongs to a certain group or class.
