Description Usage Arguments Value Examples

ivsacim is used to fit cumulative intensity models for exposure effects with instrumental variables.

`time` |
the censored event time |

`event` |
event indicator |

`instrument` |
the instrumental variable |

`IV_valid` |
whether assuming IV satisfies the exclusion restriction |

`treatment_init` |
the initial treatment assignment |

`treatment_shift_time` |
the shift time of each subject, if no shift for a subject, set as 0 |

`max_time` |
the max time that we threshold for nonconstant effect |

`max_time_bet` |
the max time that we threshold for constant effect |

`n_sim` |
the number of resampling, set as 0 if no resampling is needed |

`weights` |
optional weights used in the estimating equation |

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

`stime` |
an estimate of the baseline hazards function |

`dB_D` |
an estimate of the increment of the treatment effect |

`B_D` |
an estimate of the treatment effect |

`beta_D` |
an estimate of the constant treatment effect |

`B_D_se` |
an estimate of the variance covariance matrix of B_D |

`beta_D_se` |
an estimate of the constant treatment effect |

`by_prod` |
a byproduct, that will used by other functions |
