mira {mice}R Documentation

Multiply Imputed Repeated Analyses

Description

The mira object is generated by the with.mids(), lm.mids() and glm.mids() functions. The as.mira() function takes the results of repeated complete-data analysis stored as a list, and turns it into a mira object that can be pooled. Pooling requires that coef() and vcov() methods are available for fitted object. The mira class of objects has methods for the following generic functions: print, summary.

Usage

is.mira(x)
as.mira(fitlist)
## S4 method for signature 'mira'
print(x)
## S4 method for signature 'mira'
summary(object)

Arguments

x, object

An object containing the m fit objects of a complete data analysis, plus some additional information.

fitlist

An list of fitted objects, where each list element is a fit object. This can, for example, be produced by the by() function.

Value

call

The call that created the object.

call1

The call that created the mids object that was used in call.

nmis

An array containing the number of missing observations per column.

analyses

A list of m components containing the individual fit objects from each of the m complete data analyses.
