WebApr 15, 2024 · The variation of the samples within each chain is compared to the variance of all the samples across chains using an \(\hat {R}\)-statistic. If the \(\hat {R}\)-value is less than 1.1, we commonly assume that the MCMC chains have converged sufficiently and two MCMC chains’ combined effective sample size was larger than 3000 (out of total of ...
