This is a very difficult problem
statistically. That is, there are not many
good ideas for what SHOULD be done. Hence, there are no packages. Almost
everything you find in an applied paper (e.g. a medical journal) is wrong.

Dear Terry,
just in case it does not make too much work to
you, maybe you could give some references to
examples of wrong applications in applied medical papers.
Thanks,
Heinz
