Runs the partition-model sampler on a small synthetic forced-sort
dataset with a fixed seed and the convergence gate disabled. It exists
so examples and tests have a complete bayesqm_fit in about a second;
it is no substitute for fit_bayesian() at its defaults on real data.
Examples
fit <- demo_fit()
fit
#> bayesqm fit: exact partition (rank-order) likelihood, PX-Gibbs
#> 8 participants, 13 statements, 2 factors; grid 1-1-2-2-3-2-1-1
#> draws: 200 kept (500 iterations, burn 100, thin 2)
#> gate: passed (max Rhat 1.053; min ESS 36 bulk / 98 tail)
#> alignment: pivot draw 33, mean congruence 0.78
#> tables: compute_loadings(), compute_flags(), compute_factor_array(),
#> compute_qdc(), claims()
