I am running a mixed model for a continuous outcome using JMP Pro 17. In the output for the fixed effects parameter estimates, I have a 5-class categorical disease and the report shows the result for 4 of the 5 levels. How do I get or derive the Std Error for the parameter that is not displayed in the output report?

OK - I figured out a work around. In order to get the missing details, I changed the ordering of the categorical variables and then reran the model. Now, I can copy in the previously missing line because the referent population has changed.

Yes, I use the Expanded Estimates report when I run least sq means models/ANOVA but I don't think it is an option within the mixed models section. I am running a mixed model with 2 variables listed as random effects and others listed as fixed effects. However, I can't figure out how to get the std error/confidence interval for the unreported category.
