Repeated measures mixed model #134

Closed hhnguyen7 closed 2 years ago

hhnguyen7 commented 2 years ago

Hi, How would I approach comparison between two independent groups when within each groups there are subjects with repeated measures that are not periodic and paired?

For example: Group A (3 subjects, 10 measurements) Subject 1: 5 measurements Subject 2: 3 measurements Subject 3: 2 measurement

Group B ( 4 subjects, 4 measurements) Subject 1: 1 measurement Subject 2: 1 measurement Subject 3: 1 measurement Subject 4: 1 measurement

Thank you in advance for your help!

Hi @hhnguyen7,

If I understand your design, you will need a multi-level model, which currently cannot be done with dabestr.

You seem to have, within Group A, a repeated measures study, whilst in Group B you simply have a single datapoint for each subject. I would think only the first temporal datapoint of Group A, then would be comparable with Group B.

Hope this helps. Joses
