Hopefully an easy question: I get the error message
Error in icc.brmsfit(intercept.only) : (list) object cannot be coerced to type ‘logical’
when trying to fit an intercept only model using the package ‘sjstats’, which should work for models fit with brms. I’m thinking a problem might be that my model has a multiple membership structure with two grouping variables but it might be something completely different.
Any advice what to do about this or how else I can compute the ICC? Thanks :)
