Description Usage Arguments Value Author(s) References Examples

View source: R/gibbsmix.R

Description

This function runs a standard Gibbs sampling algorithm on a posterior distribution associated with a mixture model and 500 datapoints.

Usage

1
gibbsmix(Niter = 10^4, v = 1)

Arguments

Niter

Number of MCMC iterations

v

Scale of the normal prior

Value

The function returns a plot of the log-posterior surface, along with the MCMC sample represented both by points and lines linking one value to the next. Evaluating the log-posterior surface on a 250x250 grid takes some time.
