Logistic Regression is a classification machine learning algorithm used to classify your output. In this video, we will see how you can build a logistic regression (2 level) from scratch and then we can evaluate the performance of the same in simple easy steps. 1) Data profile 2) Data partition 3) Data modeling 4) Testing the machine learning model 5) Evaluate the model performance using a) Receiver Operating Characteristics curve b) Confusion Matrix
