extract_hazard(coxphmod)

Arguments

coxphmod

A call to coxph().

Value

A list containing:

• cbaseh: A function which returns the cumulative baseline hazard at specified time;

• inv_cbaseh: A function which returns the inverse cumulative baseline hazard at specified time.

• max_time: maximal time at which cbaseh is known;

• max_haz: value of maximal hazard (at maximum time).
