## fluctuateQ

### Description

Function called internally by drtmle to perform simultaneous fluctuation of the initial estimator of Q (i.e., solves both EIF estimating eqn and the new estimating eqn that results from misspecification of g)

### Usage

```
fluctuateQ(Y, A, W, DeltaY, DeltaA, Qn, gn, grn, a_0, reduction,
coefTol = 1000)
```

### Arguments

`Y` |
The outcome |

`A` |
The treatment |

`W` |
The covariates |

`DeltaY` |
Indicator of missing outcome (assumed to be equal to 0 if missing 1 if observed) |

`DeltaA` |
Indicator of missing treatment (assumed to be equal to 0 if missing 1 if observed) |

`Qn` |
A list of outcome regression estimates evaluated on observed data |

`gn` |
A list of propensity regression estimates evaluated on observed data |

`grn` |
A list of reduced-dimension regression estimates evaluated on observed data |

`a_0` |
A list of fixed treatment values |

`reduction` |
A character indicating what reduced dimension regression was used. |

`coefTol` |
A tolerance level on the magnitude of the coefficient that flags the result as potentially the result of numeric instability. |
