2003). An Introduction to Multivariate Statistical Analysis. New York: Wiley. G. (2000). Essential Statistics (4th edn). London: Chapman and Hall/CRC Press. htm 3 Multiple Regression WHAT MULTIPLE REGRESSION IS Multiple regression is used to assess the relative influence of a number of independent (predicting) variables when they are used to predict a dependent variable. For example, you might wish to see how patient satisfaction is predicted by the length of time the patient saw the doctor, how clearly the doctor diagnosed the condition as rated by the patient, the patient’s sex, age, complexity of medical history, etc.

HOW DO YOU DO MULTIPLE REGRESSION? The obvious initial answer to this question is ‘by telling the computer package to do it’. But you have to make some decisions about what instructions you are going to give the computer. The outcome of multiple regression depends not only on the variables which are included in it, but also on the particular strategy one tells the statistical package to use in entering the variables into the regression equation. There are three major alternatives. One is to instruct the program to enter all the independent (predictor) variables together at the start.
