Evaluate 2-D smoothing spline hazard estimates by `sshzd2d`

.

1 2 | ```
hzdrate.sshzd2d(object, time, covariates=NULL)
survexp.sshzd2d(object, time, covariates=NULL, job=3)
``` |

`object` |
Object of class |

`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. |

A vector of hazard or survival values.

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`

.

Fitting function `sshzd2d`
