Dear Statalisters,

just to add some lines to the ongoing debate about clinical trials:

the most part of the most recent literature on the economic evaluation of
clinical trials (the side of the matter I am interested in) reports examples
and exercises performed with Stata. This holds particularly true for
non-parametric bootstrap resampling and Monte Carlo simulations and, more in
general, for probabilistic sensitivity analysis of the base case findings. 

However in Italy too SAS is the most frequently used statistical package for
analysing the results of the clinical trials.

Kind Regards,

Carlo

We're all preaching to the choir here.  Most of us on this list-serve 
like Stata better than SAS.  Do we need to recount the reasons?

1) Better teaching tool than SAS.  (and it's making inroads to clinical 
trials because the epi people like it)
2) Smaller than SAS
3) You can actually reach their Tech Support people.
4) Not predatory in their business practices
5) Interactive in use (No typing a command longer than your dissertation)
6) Really good set of general tools for repeated measures (that can be 
applied to most procedures)

And so on...

Paul
