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?
Cheers!
Lucy
