I am playing with
from clogit help file.
This line works.
1. But, why strata(stratum) doesn't have a coefficient like spontaneous
2. When I remove strata(stratum) from the command, this function seems
to keep running forever. Why?
3. I think the equation for clogit looks like
In this example, I think the spontaneous is x, induced is y. So, b is
the coefficient for spontaneous and c is coefficient for induced. Where
can I find a?
