Analyzes longitudinal data with doubly robust augmented GEE approach.

1 2 |

`model` |
an object of class "formula" (or one that can be coerced to that class): a symbolic description of the model to be fitted. |

`outcomemodel` |
an object of class "formula" (or one that can be coerced to that class): a symbolic description of the ouctome model |

`data` |
a data frame containing the variables in the model. |

`id` |
a vector which identifies the clusters. The length of "id" should be the same as the number of observations. Data are assumed to be sorted so that observations on a cluster are contiguous rows for all entities in the formula. |

`family` |
a description of the error distribution and link function to be used in the model. This is a character string naming a family function. The following are permitted: "gaussian", "binomial", "poisson". |

`corstr` |
a character string specifies the working correlation structure. The following are permitted: "independence", "exchangeable", "ar1","unstructured". |

`nameTRT` |
name of the variable containing information for the treatment |

`scale` |
a numeric variable giving the value to which the scale parameter should be fixed; if NA, the scale parameter is not fixed. |

`mismodel` |
an object of class "formula" (or one that can be coerced to that class): a symbolic description of the missingness model to be fitted. |

`maxit` |
maximum iteration number for Newton-Raphson algorithm. |

`tol` |
the tolorance for the Newton-Raphson algorithm to converge. |
