Ricardo has concerns over his coming final statistics exam. In response, his professor outlines how Ricardo can estimate his grade Example of Interpreting and Applying a Multiple Regression Model We'll use the same data set as for the bivariate correlation example -- the criterion is 1st year graduate grade point average and the predictors are the program they are in and the three GRE scores. First we'll take a quick look at the simple correlations Example: The simplest multiple regression model for two predictor variables is y = β 0 +β 1 x 1 +β 2 x 2 +� The surface that corresponds to the model y =50+10x 1 +7x 2 looks like this. It is a plane in R3 with different slopes in x 1 and x 2 direction. ï10 ï5 0 ï10 5 10 0 10 ï200 ï150 ï100 ï50 0 50 100 150 200 250 19 Multiple regression allows you to include multiple predictors (IVs) into your predictive model, however this tutorial will concentrate on the simplest type: when you have only two predictors and a single outcome (DV) variable.
