Hi all,
I have been running some Bayesian HLM's with multiple latent variables
lately and seem to have hit a wall. Virtually all of the time series of the
Markov chains look well-behaved and seem to converge after a reasonable
burn-in, however one vector of coefficients wobbles and bobbles all over the
parameter space, regardless of how many iterations I allow. I have checked
my code over and over again, but it looks right. I tried different starting
values. All of this to no avail. Has anyone had this kind of problem
before and, if so, any remedies?
Thanks,
Adam
P.S. I didn't use WinBUGS, so I can't post the code easily. I wrote the
sampler myself in C++.
