The rough estimate between coxph() and cch() is same, but the lower
and upper CI and P-value are a little different. Can we exactly use
coxph() to repeat cch() using with appropriate configuration in
coxph()? Is SAS a better way(PHREG,CASECOH.SAS) to implement
time-dependent case-cohort?

and use the advice.
No, SAS will not be better. It will be different due to defaults (diffe...
