Plots in GMM with categorical outcome

Dear Linda & Bengt, I've got a four category outcome variable and want to plot the trajectories of this variable across four time points. I think I have to use the command "estimated probabilities". Here, I only get the trajectories for one category each. However, I would like to have like the "mean" trajectory of a class across all categories. If I use the command "sum of probabilities" I do not get a useful result. Can you tell me how I can plot the "mean probability" across all categories and time points? Is that somehow possible? Thank you very much 


I assume you are considering an ordinal outcome and not a nominal one. That is, you have it on the Categorical= list. For that case, I haven't seen the use of a mean probability and therefore we haven't included such an option.

Yes, I have a categorical outcome (4 categories). I understand your point but is there any possibility to present the probability of a class across all categories and not for each category separately? (as it is in the command "estimated probabilities"?)E.G. through Excel or another program? And another question: When I include the predictors in the model the option "estimated probabilites" for the plots is not available anymore. As I read in this forum, this might be due to the necessity of "numerical integration". Is there any way that I can still view the plots? Thank you very much for your help 


Q1. I don't recommend going that way. You will get critique from reviewers. Instead, consider a meaningful set of outcome categories and plot the sum of their probabilities, which is an option we offer. Q2. Try the "Adjusted..." plot option.
