Hey guys.

I’m unsure about what exactly ‘’‘TracePredictive` ( *model* , *posterior* , *num_samples* )’’’ does.

Does it allow us to sample from the posterior predictive distribution?

where the posterior predictive distribution is what you obtain by marginalizing the likelihood of the data (given the weights of the model) over the posterior distribution of the weights (obtained by using TracePosterior)

Could someone please clarify?
