I'm doing a GMM resulting in a 4-class solution. I now want to predict classes (the latent categorical variable) using auxiliary variables by using the 3-step approach (AUXILIARY = var (R3STEP);). My question concerns whether I can obtain odds ratios and confidence intervals for the regression part of the model? And how to do that?
To get the confidence limits for the Odds Ratio just exponentiate the above confidence limits for the regression parameter.

Dear Tihomir Asparouhov,
I'm doing a GMM using 3 wave data and resulted in a 4-class solution. I want to test the relationship between some wave 1 factors and the latent class. The classification was not very high (entropy=0.67) so I want to use the 3 step approach.
(1)to test the predictive value of factors, I used R3STEP so the wave 1 factors are used as predictors of latent class.
(2)to test the equality of means of factors across latent class, what should I do? Can I use DU3STEP or DE3STEP? What is the difference between them? Can I use wave 1 factors? (in your 2014 paper, you said in DU/DE3STEP variable is distal variable, what is a distal variable? is it the same with distal outcome? does it mean the variable should be assessed at wave 3?)
