## Testing for Regression Model Assumptions

 How do I check for linear regression model assumptions (linearity, homoscedasticity, normality) in SPSS? Thanks, Michael

 Michael, In a few words, look at the residuals via the residuals, casewise, scatterplot and partialplot commands. For a more serious analysis you can use the save command to save various residuals into your working datafile and then use the examine procedure. Write back if you want more info. Gene Maguin

 Gene Maguin's advice is right, only those are SUBcommands of the REGRESSION command. You may want to look at Marija Norusis' SPSS Guide to data analysis for specific advice on analyzing regression residuals in SPSS.
