hzdrate.sshzd2d {gss}

Evaluating 2-D Smoothing Spline Hazard Estimates

Description

Evaluate 2-D smoothing spline hazard estimates by sshzd2d.

Usage

hzdrate.sshzd2d(object, time, covariates=NULL)
survexp.sshzd2d(object, time, covariates=NULL, job=3) 

Arguments

object

Object of class "sshzd2d".

time

Matrix or vector of time points on which hazard or survival function is to be evaluated.

covariates

Data frame of covariate values.

job

Flag indicating which survival function to evaluate.

Value

A vector of hazard or survival values.

Note

For job=1,2, survexp.sshzd2d returns marginal survival S1(t) or S2(t). For job=3, survexp.sshzd2d returns the 2-D survival S(t1,t2).

For hzdrate.sshzd2d and survexp.sshzd2d with job=3, time should be a matrix of two columns. For survexp.sshzd2d with job=1,2, time should be a vector.

When covariates is present, its length should be either 1 or that of time.
