WebbSimple linear regression is used for three main purposes: 1. To describe the linear dependence of one variable on another 2. To predict values of one variable from values of another, for which more data are available 3. To correct for the linear dependence of one variable on another, in order to clarify other features of its variability. WebbThe regression line is based on the criteria that it is a straight line that minimizes the sum of squared deviations between the predicted and observed values of the dependent variable.
