Multiple Linear Regression | A Quick and Simple Guide
A multiple regression equation for predicting Y can be expressed a follows: (1) To apply the equation, each Xj score for an individual case is multiplied by the corresponding Bj value, the products are added together, and the constant A is added to the sum. The result is Y(, the predicted Y value for the case.

Multiple regression is a set of techniques for generating a predicted score for one variable from two or more predictor variables. And the nice thing about multiple regression is that it’s just an extension of regression with one predictor variable. All of the basic principles we covered in the last chapter still hold true in this chapter.

Regression Equation. Just as simple linear regression defines a line in the (x,y) plane, the two variable multiple linear regression model Y = a + b1x1 + b2x2 + e is the equation of a plane in the (x1, x2, Y) space. In this model, b1 is slope of the plane in the (x1, Y) plane and b2 is slope of the plane in the (x2, Y) plane. B. Regression ...

This information can be used in a multiple regression analysis to build a regression equation of the form: Salary = .5*Resp + .8*(No Super) Once this so-called regression line has been determined, the analyst can now easily construct a graph of the expected (predicted) salaries and the actual salaries of job incumbents in his or her company.

• For multiple linear regression, we will always use software to get the estimates b0, b1, b2, b3, etc. Fitting the Multiple Regression Model • Given a data set, we can use R to obtain the estimates b0, b1, b2, b3, …that produce the prediction equation with the smallest possible SSres = R code for example:

In multiple regression the marginal relationships between the response (Y) and the individual predictors (X) convey little useful information about their role in a multiple regression model! Diagnostic plots (residuals vs. fitted and residual normal quantile) for the final three-predictor model are shown below.

5. In multiple regression, it is often desirable to find the most parsimonious model (since these are easiest to interpret). To do this, we can remove any variables that are not useful in predicting Y—e.g., variables that have coefficients that are not statistically significant from zero.
