Hi ,
I been running CosmoMC and R-1 was about 0.078 the next time it was updated R-1 was 0.059 the next time it was 0.045. Is it usual to see that the drops in R-1 slow down like this between updates. The reason I ask is because the first time it was about 15, then it became 7 and then it was 1.7.
Is it Possible that some chain is just taking its time while others have converged.
Thanks
convergence issue

Re: convergence issue
You mean the values in the .log file? Doesn't sound too bad, won't converge so dramatically once the chains are all exploring the same area.
