Generate survival times according to hazard rate
h(t) \exp(μ) with h(t) the hazard rate associated with the
specified inverse cumulative hazard rate invchaz
and μ the
specified true hazard ratio mu
. See Bender et al. (2005).

|
invchaz |
the inverse cumulative (baseline) hazard rate to be used for generating survival times. Must take vector inputs! |
mu |
the true hazard ratio used to generate survival times. |
data |
an integer number of survival times to generate or
(in combination with coxphmod): a |
coxphmod |
(optional) a cox proportional hazards regression model as produced by
the function
|
Sometimes it is desirable to generate survival times from an increased hazard rate
h(t, μ) = h_0(t) exp(μ)
with h_0 the baseline hazard rate. We call exp(μ) the true hazard ratio.
A vector of survival times from subject entry time.
