I am running mixed effects logistic regression that is throwing the following error: "fixed-effect model matrix is rank deficient so dropping 1 column / coefficient"
This model is the full random-intercept model with all level-1 and level-2 predictors (20 IVs in total.. yeah is a big one) . I did not have this error when gradually adding level-1 and level-2 predictors.
After changing one categorically variable I recently created with its former version, the full-random intercept did not show the “rank error”, but the b estimates and p-values changed.
Does anyone have an idea what's going on? Should I disregard the results of the model with the "rank deficient" error "?
