Summarize relational property of overall prior and posterior draws
set2set(priors, posteriors, par, bins = 20)
A posterior::draws_rvars of dimension(n_iterations=1, n_chains=n_sbc_iterations, n_variables=n_variables) which stores prior draws
A posterior::draws_Rvars of dimension(n_iterations=n_posterior_draws, n_chains=n_sbc_iterations, n_variables=n_variables), which stores fitted posterior draws
names of parameter to summarize
number of bins for prior and post density
