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. WebTrace plots that show the value of each parameter through “time” should show good “mixing”. Trace plots from separate “chains” should converge on the same values. R ^ < 1.02 shows that variance across multiple chains is the same. Software comparison Steps: Install Stan or OpenBUGS or JAGS Write down the model (s) you want to fit on paper.
