This uses a Repeated measures analyse as an introduction to the Mixed models (random effects) option in SPSS.
Demonstrates different Covariance matrix types & how to use the Likelihood ratio test to evaluate different models.
First an inappropriate standard regression model is developed then one with a random intercept ( considering the patient a level 2 variable) and finally a random intercept+ slope model, each is evaluated using the likelihood ratio test (see previous video for more details on obtaining chi square p value).
The example is from Twisks excellent book - applied multilevel analysis p.91-95 with him using the free package MLWin
