nelsonaalen_npdf R Documentation
Nelson-Aalen estimates of group-specific cumulative hazard from a nonparametric discrete frailty model
Description
Nelson-Aalen estimates of group-specific cumulative hazard from a nonparametric discrete frailty model
Usage
nelsonaalen_npdf(x)
Arguments
x
A fitted nonparametric discrete frailty model, as returned by npdf_cox with estK=FALSE.
Value
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.

Examples
x = npdf_cox( Surv(time, status) ~ x, groups=family, data=weibdata2030, K = 2,
estK=FALSE, eps_conv=10^-4)
object = nelsonaalen_npdf( x )
