The print method displays summary statistics for the parameters and two MCMC diagnostic measures:
Rhat
is the 'potential scale reduction factor', which is 1 on convergence; if any parameter has a value > 1.05, rerun with increased burnInSteps
. See gelman.diag
.
n.eff
is the sample size adjusted for autocorrelation; for stable estimates of credible intervals this should be > 10,000. Rerun with increased numSavedSteps
or increased thinSteps
. See effectiveSize
