x |
A fitted nonparametric discrete frailty model, as returned by |
A list of objects of length equal to the number of groups in the data. Each component is a list, equivalent to the output of survfit
called for the corresponding group with type="fh"
, but with two additional components:
y0
: -log
of the survival estimate
sfun0
: a step function for y0
in terms of time, estimated using stepfun
