Which BUGS should one use?
Hello ALL!
Some times ago I started to learn and play with Bayesian stuffs. Many
advice use of WinBUGS for Bayesian inference Using Gibbs Sampler.
However, WinBUGS is discontinued, and now, development is under
OpenBUGS. I wasn't lazy, so I installed both and tried out. In more than
90% of cases they give comparable outcome. But in few cases I got
substantial differences. Recently, I read nice

Best practices for handling very small numbers?
Greetings
I have been experimenting with sampling from posterior distributions using
R. Assume that I have the following observations from a normal distribution,
with an unscaled joint likelihood function:
normsamples = rnorm(1000,8,3)
joint_likelihood = function(observations, mean, sigma){
return((sigma ^ (-1 * length(observations))) * exp(-0.5 * sum(
((observations - mean ) ^ 2)) / (sigma
