I have fit a model with my in-sample data. I am trying to simulate a distribution of predictions for each row in my hold out data set.
So far I found the posterior_predict function, but this returns simulations of the in sample data updated from the new data. This is not what I am looking for.
I am looking for something analogous to applying the
simulate() function with a fit object from
How do I simulate a full distribution from each row of new data?
