Hi All,
I'd like to created graphic depictions of interval estimates for the mean
of a group of attributes compared across two samples. So, for example, x1 x2
and x3 are questions answered in two surveys and, rather than doing
frequentist t-tests of their differences, I'd like to produce Bayesian HPD's
of either the means themselves (and see where they do or do not overlap) or
produce Bayesian HPD's of the differences.
I was wondering if anyone had experience doing this sort of thing in Zelig
and/or could point me to an example.
Many thanks,
Joe Retzer
