Is it possible to add “data” to the observed object in an arviz object? I have significant outliars that are few in quantity but massive in moving my model’s prediction distribution in a bad way. I’d like to train the model on an “outliar-corrected” data set, but run the
az.plot_ppc using the actual data set.
I have added coordinates to an arviz object prior, but not data. Is that possible to add additional data to the observed then use an
arg to tell arviz which to pull?
