stackMI | R Documentation |

Runs an `rmsb`

package Bayesian fitting function such as `blrm`

separately for each completed dataset given a multiple imputation result such as one produced by `Hmisc::aregImpute`

. Stacks the posterior draws and diagnostics across all imputations, and computes parameter summaries on the stacked posterior draws.

```
stackMI(
formula,
fitter,
xtrans,
data = NULL,
n.impute = xtrans$n.impute,
dtrans = NULL,
derived = NULL,
subset = NULL,
refresh = 0,
progress = if (refresh > 0) "stan-progress.txt" else "",
file = NULL,
...
)
```

`formula` |
a model formula |

`fitter` |
a Bayesian fitter |

`xtrans` |
an object created by |

`data` |
data frame |

`n.impute` |
number of imputations to run, default is the number saved in |

`dtrans` |

`derived` |

`subset` |
an integer or logical vector specifying the subset of observations to fit |

`refresh` |
see rstan::sampling. The default is 0, indicating that no progress notes are output. If |
