Things never seem to work out when you need them to.  /sigh

My log posterior traceplots are not working out.  For some reason my log posterior traceplots (data set 1) are converging to each other (even though the individual parameter posteriors converge to different values).

And my tuning function is not working out.  I’m afraid I’m going to have to adjust the tuning parameter for each latent space position separately.  But I’m not even sure that’ll work.   I really don’t understand why things aren’t working.

I think I need to test my one of my simulated simple data sets with this sampler and see if I can tune things. (Possible “to do” for this weekend while I’m traveling?)

***So I’m not sure what’s going on now.  At the airport and working on the log posterior traceplots.  First of the first – if I work with just my medians, the log posterior is close to the true log posterior.  If I look at a traceplot, not so much.

I can’t seem to figure out if it’s a coding issue (it must be, right?)
