Logistic Regression examples in python & R

In every algorithm of machine learning, there is an approach that is unique yet easily interpretable. Logistic regression is one such algorithm with an easy and unique approach. It is very often used in the credit and risk industry for its easy intuition on predicting the chances of default and risk cases. It is indeed quite a challenge to break down most of the algorithms due to their black-box nature and their hard to find parameters, but logistic regression outperforms all. So it is time to break down the entire algorithm and draw some inferences.
