R: Evaluating 2-D Smoothing Spline Hazard Estimates

hzdrate.sshzd2d {gss} | R Documentation

## 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`.
