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

1 2 | ```
tsriadditive(survtime, cause = NULL, treatment = NULL, IV = NULL,
covariates = NULL)
``` |

`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 |

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 |
