Multiple Linear Regression


Linear regression is an approach to model the relationship between a normally distributed interval outcome variable y and one or more predictor variables denoted X. The case of one predictor variable is called simple linear regression. For more than one predictor  variable, it is called multiple linear regression. Multiple linear regression is very similar to simple linear regression, except that in multiple regression you have more than one predictor variable in the equation.
