Philip Ender <ender97@gmail.com> has a question about -pweight-s and survival
data:

Let's assume the dataset has been -stset- using the -id()- option to identify
each person.  If 'expanded the data to person-period form' is essentially the
same as using -stsplit-, then leave the -pweight-s as they are.  Otherwise
we would need more information to comment any further, although we suspect
that the -pweight-s should still remain untouched.
