Notes

  • Added multiple chains, randomized starting points for each chain, and confirming Gelman-Rubin convergence criteron via autojags.
  • Some edits to adapt the extraction of posteriors from the multiple chains.
  • Stange behavior in jags.parallel SO/16723036, looks like an annoying bug.
  • Ah-ha, and now a nice solution to this problem via do.call.

When running on farm, try to remember: (yes it’s in the run.sh script already).

module load gcc R jags

This appears to result in greater uncertainty:

Suggesting the earlier appearance of convergence occurs only thanks to starting conditions close to the optimum?

  • Grr, why is dcast not more intuitive to me. Thank you SO folks. SO/16722117
