Multiple regression is of two types, linear and non-linear regression. Multiple Regression Formula. The multiple regression with three predictor variables (x) predicting variable y is expressed as the following equation: y = z0 + z1*x1 + z2*x2 + z3*x3. The “z” values represent the regression weights and are the beta coefficients.

Hierarchical Multiple Regression. In hierarchical multiple regression analysis, the researcher determines the order that variables are entered into the regression equation. The researcher will run another multiple regression analysis including the original independent variables and a new set of independent variables. 2017-10-30 Multiple regression is an extension of linear regression into relationship between more than two variables. In simple linear relation we have one predictor and one response variable, but in multiple regression we have more than one predictor variable and one response variable. The general mathematical equation for multiple regression is − Kap 8: Introduktion till multipel regressionsanalys.
