ibind: Enlarge number of imputations by combining 'mids' objects

In stefvanbuuren/mice: Multivariate Imputation by Chained Equations

Enlarge number of imputations by combining mids objects

Description

This function combines two mids objects x and y into a single mids object, with the objective of increasing the number of imputed data sets. If the number of imputations in x and y are m(x) and m(y), then the combined object will have m(x)+m(y) imputations.

Usage

ibind(x, y)

Arguments

x	A mids object.
y	A mids object.

Details

The two mids objects are required to have the same underlying multiple imputation model and should be fitted on the same data.

Value

An S3 object of class mids
