Logistic Regression is a statistical method of classification of objects. In this article we implemented logistic regression using Python and scikit-learn. Yet, Logistic regression is a classic predictive modelling technique and still remains a popular choice for modelling binary categorical variables. In our last post we implemented a linear regression. By binary classification, it meant that it can only categorize data as 1 (yes/success) or a 0 (no/failure). In this tutorial of How to, you will learn ” How to Predict using Logistic Regression in Python “. We will be using Scikit learn to build the Logistic Regression model. Another advantage of logistic regression is that it computes a prediction probability score of an event. Difference Between the Linear and Logistic Regression. Prerequisite: Understanding Logistic Regression User Database – This dataset contains information of users from a companies database.It contains information about UserID, Gender, Age, EstimatedSalary, Purchased.
