"WebLinear regression is a statistical method used to create a linear model. The model describes the relationship between a dependent variable $y$ (also called the response) as a function of one or more independent variables $X_i$ (called the predictors). The general equation for a linear model is: \[y = \beta_0 + \sum \ \beta_i X_i + \epsilon_i\] " - Example of linear model
