1.4 Multiple Regression . Now, let’s look at an example of multiple regression, in which we have one outcome (dependent) variable and multiple predictors. For this multiple regression example, we will regress the dependent variable, api00, on all of the predictor variables in the data set.

Easier Notation? The multiple regression model can be written in matrix form. Suppose, for example, that y is the lifetime of a certain tool, and that there are 3

To get a better feel for the graphic representation that underlies multiple regression, the exercise below allows you to explore a 3-dimensional scatterplot. MULTIPLE REGRESSION EXAMPLE For a sample of n = 166 college students, the following variables were measured: Y = height X1 = mother’s height (“momheight”) X2 = father’s height (“dadheight”) X3 = 1 if male, 0 if female (“male”) Our goal is to predict student’s height using the mother’s and father’s heights, and sex, where sex is Multiple Regression: Examples Population Regression Equation Population Regression Equation The following example demonstrates an application of multiple regression to a real life situation. 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.
