tsriadditive: Fitting Additive Hazards Models with Two Stage Residual...

In tsriadditive: Two Stage Residual Inclusion Additive Hazards Estimator

Description

tsriadditive is used to fit additive hazards models with two stage residual inclusion method.

Usage

tsriadditive(survtime, cause = NULL, treatment = NULL, IV = NULL,
  covariates = NULL)

Arguments

survtime	the event time
cause	the indicator records the cause. Default to all one. Zero means right censoring. Greater than or equal to two means other cause.
treatment	the treatment variable, can be null
IV	the instrumental variable
covariates	all the observed confounders

Value

tsriadditive returns an object of class "tsriadditive". An object of class "tsriadditive" is a list containing the following components:

coef	an estimate of the coefficients
baseline	an estimate of the baseline hazards function
vcov	an estimate of the variance covariance matrix of coef
byprod	a byproduct, that will used by other functions

Examples

survtime <- rexp(100)
cause <- rbinom(100, 1, 0.7)
treatment <- rbinom(100, 1, 0.5)
IV <- rnorm(100)
covariates <- rnorm(100)
fit <- tsriadditive(survtime, cause, treatment, IV, covariates)
