Dear Jorge,
For the statistical analysis of longitudinal data we used the "Two Stage
Model" (TSM) and the "Linear Mixed Effects".
Our intergroup LME results (2 groups, 2 time points) had many
similarities with TSM results. Then with TSM we analysed the intragroup
changes (one group, and 2 time points). We tried to do the same analysis
with LME but the results are very different, so I suppose that the
contrast was incorrect.
For the intergroup analysis (2 groups x 2 time points) I used
/lme_mass_fit_vw/ and CM.C = [0 0 0 1];
For the intragroup (1 group x 2 time points) I also used
/lme_mass_fit_vw/ but CM.C = [0 1];
Can you please tell me if the CM.C is correct ? or is there something
else I should change ?
Thanks,
Best regards,
Alex.
