Mar 24, 2018 at 7:24 comment added michael @mef Thanks. I meant the trace of a matrix (the residual covariance matrix estimated from the MCMC samples).
Mar 22, 2018 at 9:01 comment added mef The word "trace" has multiple meanings. You are interested in the trace of a matrix (the sum of the main diagonal elements). By contrast, a "trace plot" is a standard MCMC graphical diagnostic tool. I mention this because your question could involve both meanings. In fact, you could make a trace plot of the trace!
