Overview

Regression (or regression analysis) is a statistical process for estimating the relationship among variables. Typically, there's an output or dependent variable, and one or more predictors or features. Regression models estimate how the "typical" value of the output variable changes when one of the future is changed, but others are fixed constant.

Regression refers to the estimation of continuous response (dependent) variables, as opposed to the discrete response variable used in classification.

Linear Regression

A common example of regression analysis is linear regression where the dependent variable is modeled as a linear function of the features.
