Hi Duncan,
Thanks for having a look at this. Find attached a zip with all the
relevant files to run the simulation. I am running this on Windows XP,
R version 2.3.1.

Hi,
I am finding that I get quite different results when I interchange the
following equivalent lines for sampling from a beta distribution in my
r script. The rbeta line is correct judging by the summary statistics of
the simulated values, while the qbeta line consistently leads to a
higher mean

Hi Duncan,
I had also validated the logic with a simple test which is why I was
surprised by the differences I was seeing from tthe more complex simulation.
I am running R on a Windows 2000 - I'll have to check which version at my
desk tomorrow
