Dear Wolfgang, thank you very much for the references. There's always a lot to learn! Best, Emily Am 31.03.2018 um 17:52 schrieb Viechtbauer Wolfgang (SP): > Convergence problems are difficult to anticipate. But in general, they are...

Dear Isabel, I'm not an expert in meta-analysis, so I have to leave your question - if multivariate MA makes sense at all in your case - open to the experts around. If your different outcomes do measure different symptoms...

Dear Wolfgang, may I just chimp into your conversation, since after reading it, I am getting quite uncertain about our own analysis... We have a combination of studies with multiple treatments compared to the same control group (in some studies...

Dear James, thank you so much for your quick reply! In fact, the distinction between treatment conditions is of interest, since my moderators/covariates differ between the different conditions within the studies that include multiple groups. So, I have used...

Update: I had a closer look at the models and what changes in the estimates: When I add "id" as another random effect level, I find that sigma^2 is 0.000 for Outcome and id (or very near to...
