Least Squares Regression
The least-squares regression line is the best fitting line to bivariate data. An independent variable is used to predict a value of a dependent value.
By investigating the residuals, the difference between the predicted and actual value of the dependent variable, is used as a diagnostic check on the model.
Data can be transformed in order for the residuals to look like they come from a normal distribution.
