Hi,
Hope you guys had a Merry Christmas and will have a Happy New Year!
Question: tried running stcox with expanded interaction command "xi"
including 2 variables. Each variable name has 4-6 subgroups. When
typed the following:
xi: stcox dim i.mast_yn i.lact, nohr
the stcox output was empty. There were no P-values, no coefficients,
nothing at all. If I were to run it as:
xi: stcox dim i.mast_yn lact, nohr
there was some output available. What's the issue here?? What else
could cause the processing to "freak out" as such and show no results?
Unless you provide more details, eg, output of stcox, summaries or
tab's of your variables, etc, I would consider it rather unlikely that
it would be possible to answer your questions.
