crr.wt.KM: Regression modeling of subdistribution functions using...

Description Usage Arguments Details Value Author(s) References

Description

Fits a subdistribution hazards regression model using the Kaplan-Meier weight. This is the same model as Fine and Gray (1999).

Usage

1
crr.wt.KM(t, ic, z, variance, var.conservative)

Arguments

t

a vector of observed times.

ic

a vector of cause indicators.

z

a matrix of covariates for fitting the model.

variance

Includes variance calculation if TRUE, Skips variance calculation if FALSE.

var.conservative

Includes minor term of variance of beta if FALSE, no minor term for variance of beta if TRUE.

Details

More details are given in the reference.

Value
