This article is a down-to-earth guide on logistic regression, cutting through the technical jargon to explain the method’s nuts and bolts. We’ll walk through the basics, from understanding the sigmoid function to making sense of those coefficients. Whether you’re just starting with data science or want a refresher on logistic regression, this guide is here to demystify the process and make it practical for your time series projects.

# Introduction to Logistic Regression

Logistic regression is a statistical method used for binary classification tasks, where the outcome variable is categorical and has two classes (0 and 1). It’s an extension of linear regression but adapted for predicting the probability of an observation belonging to one of the two classes.

In logistic regression, the logistic function (also called the sigmoid function) is used to map the linear combination of input features to a probability between 0 and 1.

The sigmoid function, also known as the logistic function, is a mathematical function that maps any real-valued number to a value between 0 and 1. It’s characterized by its S-shaped curve…
