Do you have any idea, form this limited data, what could cause that?
I can provide more details about the grid object if you request, but providing all the data will be challenging...
I have a longitudinal study. I want to assess trend in LS-means. Variable "visit" is ordinal factor with
Levels: Month 6 < Month 12 < Month 20
The model recognizes the ordered factor.
Now qdrg() (I need it for some reasons)
OK, it works here:
Now trying obtain the same in multiple imputation manner. I cannot attach the data, can only describe the problem.
gives a list of analyses. Coefficients:
Pooling it:
Maybe the bhat is the issue?
Now all estimates are the same:
and finally

Data for the simple, working case.:
