How to add already made predictions to data frame #173

Closed PhoenixB closed 5 years ago

PhoenixB commented 5 years ago

Dear Matthey,

Is it possible to add already calculated predictions from a brms model, i.e. pp_average.brmsfit() in a tidy format to the original data frame circumventing add_predicted_draws()?

Kindest regards, Pascal

Yes, certainly! That is what add_draws() is for. You would need to use summary = FALSE with pp_average(). Let me know if you have trouble getting it to work.

Ah cool! This one slipped my attention! Thank you very much! I suppose it is also possible with ordinal brms models? Edit: it definitely works! Thanks!
