What is regression analysis?

Regression analysis is a statistical method used to model the relationship between a dependent variable and one or more independent variables. It is used to understand and predict the value of the dependent variable based on the values of the independent variables. The goal of regression analysis is to find the best-fitting line or curve that represents the relationship between the variables. It helps in understanding the strength and direction of the relationship, as well as making predictions or estimating the impact of changes in the independent variables on the dependent variable.
