Run (or reuse) the chain behind an MCMC posterior's sample() method

The body sample.nsbi_mcmc_posterior() runs regardless of whether the underlying fit is an nle() or nre(). Which sampler runs is read off the posterior object, so nothing here needs to know which kind of fit produced it.

Usage

mcmc_draws(post, n, obs, refresh, verbose)

Arguments

post

An MCMC-sampled nsbi_posterior.

n

Number of draws.

obs

Observation to condition on, or NULL for the posterior's own.

refresh

Force a new run even when a cached one would do.

verbose

Report sampling progress.
