Dear Hugh,
the output of -stset- could
add some suggestion about what happens when -stcompet- is used to
generate the cumulative incidence function.
Anyway, I would be pleased
to give some further insight to your problem.
To this aim you should
send me privately a part of your data set and do file.
When the
problem has been resolved, we may send a mail to the List whit more
detailed comments.
Best wishes.
Enzo
