I'm currently writing a SAP where I'll add a mixed model. Do you guys have a good online reference document on this subject ?
I mean, where I can see how to perform this model using SAS and the points I need to pay attention to!
Thank you a lot
Thank you for your answers. Let take two examples for more understanding.
Suppose I have a continuous variable (CV) to explain.
If I have on the one hand: (1)
CV measures and an other categorical variable at different visits
and on the other hand: (2)
CV measures and other...
I have two questions that I would like to clarify, please.
1. What is the difference between a repeated measure ANOVA and a mixed model?
2. Can we use a mixed model when we have only two repeats? for example only 2 visits.
Thank you in advance
If I understand correctly, the variable to be analyzed is continuous, right? If so, a repeated measurement ANOVA would be suitable.
I think it would be better to describe your data and what you have already done and we can help you better.
