"""
Demo of using `Gibbs` sampling with `ESS` update for one set of parameters and
`GibbsConditional` for another. Demo model is a standard multiple linear
regression model with Gaussian priors for the coefficients and Inverse Gamma
prior for the variance of the error terms. Weakly / non-informative priors are
used. Results are benchmarked against the inference from a model sampled
entirely using NUTS.
