Logistic Regression, Made Simple!!!

Logistic Regression, Made Simple!!! What is logistic regression, and how does it predict pass or fail? Logistic regression is one of the oldest tricks in statistics and one of the most popular tools in machine learning. In this video, we build it from scratch: why straight lines fail on yes-or-no questions, what the S-shaped curve really means, how to turn probabilities into decisions, and how the curve gets fit with maximum likelihood.
