Using Linear Mixed Models to Analyze Repeated Measurements

A physician is evaluating a new diet for her patients with a family history of heart disease. To test the effectiveness of this diet, 16 patients are placed on the diet for 6 months. Their weights and triglyceride levels are measured before and after the study, and the physician wants to know if the weights have changed.

This example uses the file dietstudy.sav. See the topic Sample Files for more information. Use Linear Mixed Models to determine whether the diet has an effect on the weights of these patients.

Because the data file was originally set up for analysis in the GLM Repeated Measures procedure, you need to restructure the file from variables to cases.
