mira-class: Multiply imputed repeated analyses ('mira')

mira-classR Documentation

Multiply imputed repeated analyses (mira)

Description

The mira object is generated by the with.mids() function. 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.

Details

In versions prior to mice 3.0 pooling required only that coef() and vcov() methods were available for fitted objects. This feature is no longer supported. The reason is that vcov() methods are inconsistent across packages, leading to buggy behaviour of the pool() function. Since mice 3.0+, the broom package takes care of filtering out the relevant parts of the complete-data analysis. It may happen that you'll see the messages like No method for tidying an S3 object of class ... or Error: No glance method for objects of class .... The royal way to solve this problem is to write your own glance() and tidy() methods and add these to broom according to the specifications given in https://broom.tidymodels.org.

#'The mira class of objects has methods for the following generic functions: print, summary.

Many of the functions of the mice package do not use the S4 class definitions, and instead rely on the S3 list equivalent oldClass(obj) <- "mira".

Slots

#'

call:
