Hi all, I used both OpenBugs and R function bugs{R2WinBUGS} to run a linear mixed effects model based on the same data set and initial values. I got the same summary statistics but different posterior samples. However, if I order these two sets of samples, one is generated from OpenBugs and the other is generated from R, they turn to be the same. And the samples from R do not have any autocorrelation. I do not know why and how this R function destroy the orders of posterior samples. Have anyone ever met this situation before? Any idea is appreciated.
