Hi,

I have a dataset and our dependent variable is measured at five different time points. we want to know if there is a difference between the two groups that we are studying (control and experimental). We also want to know if the dependent variable response is changing over time.

I found from various resources that a mixed model approach would be appropriate for  my analysis. However, I would like to know what is the difference in the test statistic between the mixed models and repeated measures ANOVA (GLM)? do both these approaches use F-test for testing the significance effect? is there any difference in the way F-test statistic is computed between these two approaches?

Thanks.
