Many Thanks to every one for your helpful response.
It gave me valuable insight. I went back and checked the formula for the
prior distribution. The correct formula is
1/sqrt[(x-a)**2+b] , -Inf<x<Inf
Which is different than what I mistakenly sent you earlier. Could you
please tell me what distribution can I use for this formula in winbug13.
If I am stuck with cauchy prior, is this a source of a problem for obtaining
reliable and stable estimate for the mean and variance for the posterior
distribution?
Thanks
Lamya
