Re: [R] Baysian model averaging method

          I'm not certain what you are asking. Do you want to fit a time series model using Bayesian Model Averaging (BMA), or do you want to predictions with confidence intervals from a BMA fit or both? For any of these, I suggest you start with the posting guide! "www.R-project.org/posting-guide.html" and with "RSiteSearch" in particular. I just got 31 hits from 'RSiteSearch("Baysian model averaging")', which included discussions of the BMA and ensembleBMA packages as well as an article on "BMA: An R package for Bayesian Model Averaging" by Raferty, Painter and Volinsky, 3 of the 4 authors of the BMA package.

          I couldn't find a function for a BMA time series fit. If I wanted that, I'd probably start by asking the maintainers for "BMA" and "ensembleBMA" (cc'ed on this reply) and by reading the code for the nearest things I could find. I'd make local copies of one or more functions and try to walk through the code line by line until I thought I understood it well enough to modify it to do what I wanted. With luck, someone may reply to this email with hints or even code that might make that task easier.

	  hope this helps,

p.s. If I had understood your question better, I might have been able to supply more useful suggestions.
