`mipo`

: Multiple imputation pooled objectThe `mipo`

object contains the results of the pooling step.
The function `pool`

generates an object of class `mipo`

.

`mipo(mira.obj, ...)`# S3 method for mipo
summary(object, type = c("tests", "all"),
conf.int = FALSE, conf.level = 0.95, exponentiate = FALSE, ...)

# S3 method for mipo
print(x, ...)

# S3 method for mipo.summary
print(x, ...)

process_mipo(z, x, conf.int = FALSE, conf.level = 0.95,
exponentiate = FALSE)

mira.obj

An object of class `mira`

…

Arguments passed down

object

An object of class `mipo`

conf.int

Logical indicating whether to include
a confidence interval. The default is `FALSE`

.

conf.level

Confidence level of the interval, used only if
`conf.int = TRUE`

. Number between 0 and 1.

exponentiate

Flag indicating whether to exponentiate the coefficient estimates and confidence intervals (typical for logistic regression).

x

An object of class `mipo`

z

Data frame with a tidied version of a coefficient matrix

The `summary`

method returns a data frame with summary statistics of the pooled analysis.

An object class `mipo`

is a `list`

with three
elements: `call`

, `m`

and `pooled`

.

The `pooled`

elements is a data frame with columns:

`estimate` |
Pooled complete data estimate |

`ubar` |
Within-imputation variance of `estimate` |

`b` |
Between-imputation variance of `estimate` |

`t` |
Total variance, of `estimate` |

`dfcom` |
Degrees of freedom in complete data |

`df` |
Degrees of freedom of $t$-statistic |

`riv` |
Relative increase in variance |

`lambda` |
Proportion attributable to the missingness |

`fmi` |
Fraction of missing information |

The names of the terms are stored as `row.names(pooled)`

.

The `process_mipo`

is a helper function to process a
tidied mipo object, and is normally not called directly.
It adds a confidence interval, and optionally exponentiates, the result.
