When I run a logistic regression, I obtain the following ORs. However some of the categories I used have 3 levels (u2, u3 and u4) but just one ratio. How can I calculate the odds for each of the 2 other categories based on the first? Should I be using the thresholds in the model results?
Also, how can I get Mplus to do two separate regressions, split by gender? Is it by using the CLASS function?
There should be two odds ratios for a variable with three categories. Please send the full output and your license number to firstname.lastname@example.org.
You can use the USEOBSERVATIONS option to do an analysis for a subset of the sample. You can use the GROUPING option to do multiple group analysis.

Good morning. In the MLM setting, I easily understand how to compute the odds ratios from the fixed effects. In addition, I realize I can create a CI by first computing the CI for the beta coefficients and then exponentiating them. But, what formula would you suggest for estimating the ORs SE?
