Samples parameters from the posterior and pushes them back through the simulator, giving predictive data to compare against the observation.

Usage

posterior_predictive(post, simulator, n = 1000L, x = NULL, chunk_size = NULL)

Arguments

post: An nsbi_posterior object.
simulator: The simulator.
n: Number of predictive draws.
x: Observation to condition on (defaults to x_obs).
chunk_size: Rows per simulator call; see nsbi_parallel.

Value

An n x d matrix of simulated data from posterior parameter draws.
