Usage

subgroup_average_posterior(posterior_samples, groups, weights = NULL)

Arguments

posterior_samples	A matrix of posterior samples, with MCMC draws down the rows
groups	A factor defining the desired subgroups. Must have length ncol(posterior_samples)
weights	Optional weights, for computing a weighted subgroup average

Details
