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).
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.
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.

Mar 29, 2024 · linear regression, in statistics, a process for determining a line that best represents the general trend of a data set. The simplest form of linear regression involves two variables: y being the dependent variable and x being the independent variable. The equation developed is of the form y = mx + b, where m is the slope of the regression line ...
Apr 23, 2022 · Learning Objectives. Identify errors of prediction in a scatter plot with a regression line. 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 Y.
