Bayesian data mining
Hi, I need a help to know whether I can perform the following in R:
I have a set of observations (Ns) and each observation is drawn from a
poisson distribution with an unkown mean, lambda. The set of lambdas in
their turn are drawn from a common prior distribution which is supposed to
be a a mixture of two gamma distributions.
Is there a way to determine the poisson means in R, given the Ns and

Re: Excel 2003
I have successfully installed Visio2003 on Wine 1.1.6, Kubuntu Hardy 8.04 x86.
However, upon starting, the splash screen shows, and behind (!) it an error windows pops up.
In the console, I see the following error:
fixme:keyboard:X11DRV_GetKeyboardLayout couldn't return keyboard layout for thread 0017
