Functions for Analysis of Nested Multiply Imputed Datasets

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.

NestedImputationList( datasets )

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

# S3 method for 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.
