This tutorial covers many facets of regression analysis including selecting the correct type of regression analysis, specifying the best model, interpreting the results, assessing the fit of the model, generating predictions, and checking the assumptions.
In statistics, linear regression is a statistical model which estimates the linear relationship between a scalar response and one or more explanatory variables (also known as dependent and independent variables).
Linear regression is a process of drawing a line through data in a scatter plot. The line summarizes the data, which is useful when making predictions.

A linear regression equation describes the relationship between the independent variables (IVs) and the dependent variable (DV). It can also predict new values of the DV for the IV values you specify. In this post, we’ll explore the various parts of the regression line equation and understand how to interpret it using an example.
Apr 23, 2022 · In simple linear regression, we predict scores on one variable from the scores on a second variable. The variable we are predicting is called the criterion variable and is referred to as \(Y\). The variable we are basing our predictions on is called the predictor variable and is referred to as \(X\).
