I get an error message “Fitting imputed model 2
Error: All ‘mu’ parameters are specified so that the right-hand side of ‘formula’ is unused.” when running the following code:
SuggestedManagement ~ ieta_hist.age + knot + bmi + invisible.endometrium + bright.edge + col.score + single.dominant + non.uniform + cyst + endometrial.thickness
+ (1 | rater),
data = imp,
family = categorical(),
The model runs fine when I don’t use multiple imputation. I reinstalled brms from github after reading about the bug reported (https://github.com/paul-buerkner/brms/issues/455). The problem occurs with the second imputed dataset, sampling occurs normally for the first. Inspecting the second imputed dataset doesn’t reveal anything strange.
What does the error message mean?
