arm, there is an option to not drop baseline factors when creating a design matrix. I am porting an
arm::bayesglm model to use
rstanarm::stan_glm but can’t get comparable results because
arm::stan_glm always drops the baseline factors.
- Is there an option somewhere to not drop baseline factors when creating the design matrix?
- Does it not exist because the expectation is that one would use
rstanarm::stan_glmerin this situation?
If it does not exist, is there interest in a patch to add it?
