I’ve read the Pyro documentation for
Predictive() function, and I have a question about the contents of the documentation.
The documentation states that
Predictive() generates the samples from the predictive distribution conditioned on the parameter
posterior_samples. Does that mean I have to specify the
posterior_samples in order to properly draw the posterior samples from the predictive distribution? If I do not specify the
posterior_samples, but only specify the
guide, does the
Predictive() function in this case still draw samples from the predictive distribution?
