Chris Ryan asked (rethorically?):
Are there *any* circumstances in which stepwise multiple regression
would be the preferred approach?
--------------------------------
I can think of one example:
In the thalidomide disaster an epidemic of rare malformations occurred.
There were no strong, but dozens of weak hypotheses about the etiology.
In such a situation I think an extensive case-control study followed by
a stepwise logistic regression analysis is the most sensible thing to
do.
I can think of no other situations...
