Hi.
I tried to search an answer in previous posts but i didn't find anything.. anyway i apologize if i'd sound repetitive!
I have a database with 30 observations (patients), each of them evaluated with various (about 10) clinical evaluation scale, repeated at three time points (before, after treatment and after a period of follow up - first and second time point are fully filled, at third there are some missing values).
I divided patients into three different groups and i want to test if there are differences within and between three groups at second and third time point.
Searching into stata manual and on statalist i found many information about using xtmixed with one dependent variables and interactions between independent ones and time-points but..
if i have more than one dependent (in my database, multiple scores of evaluation scale - continuous and not -) i must run a mixed model for each one or is there a command to perform a single analysis?
Thank you
Emanuele
