I have a brms model with 8 continuous and 3 ordinal responses, and I would like to make a marginal_effects plot for one binary predictor per response. When I run the code, I get a warning that recommends using
categorical=TRUE for the ordinal responses. However, doing this throws an error, since I have continuous responses. Is there a workaround here?
Alternatively, is there some way to only calculate the effects for a subset of responses?
