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

Hi, When I fit the mixed-effects model by lme, I got the convergence error code = 1 message = iteration limit reached without convergence (9). Even after I increase the iteration numbers, it still did not work. The only way I found to avoid the error message is to increase the number of
