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.
