WebFeb 5, 2024 · A traceplot can tell us how well the sample is exploring the space of the posterior distribution. If we have several plots from several chains (Stan does 4 by default) that seem to be noisy and overlap, that’s a good indication that the chains have converged to the posterior distribution. WebAug 5, 2015 · It would be useful to have the traceplot() function be able to draw separate plots for each chain. At the moment all of the chains are overplotted, which makes it hard to see if specific chains are behaving differently to the rest. I think one good approach would be to have a grid of plots, with one row per parameter and one column per chain.
