NestedImputationList: Functions for Analysis of Nested Multiply Imputed Datasets

In alexanderrobitzsch/miceadds: Some Additional Multiple Imputation Functions, Especially for 'mice'

Functions for Analysis of Nested Multiply Imputed Datasets

Description

The function NestedImputationList takes a list of lists of datasets and converts this into an object of class NestedImputationList.

Statistical models can be estimated with the function with.NestedImputationList.

The mitools::MIcombine method can be used for objects of class NestedImputationResultList which are the output of with.NestedImputationList.

Usage

NestedImputationList( datasets )

## S3 method for class 'NestedImputationList'
print(x, ...)

## S3 method for class 'NestedImputationResultList'
MIcombine(results, ...)

Arguments

datasets	List of lists of datasets which are created by nested multiple imputation.
x	Object of class NestedImputationResultsList
results	Object of class NestedImputationResultsList
...	Further arguments to be passed.

Value

Function NestedImputationList: Object of class NestedImputationList.

Function MIcombine.NestedImputationList: Object of class mipo.nmi.
