mice.impute.synthpop: Using a synthpop Synthesizing Method in the mice Package

Description

The function allows to use a synthpop synthesizing method to be used in the mice::mice function of the mice package.

Usage

mice.impute.synthpop(y, ry, x, synthpop_fun="norm", synthpop_args=list(),
     proper=TRUE, ...)

Value

A vector of length nmis=sum(!ry) with imputed values.

Arguments

y

Incomplete data vector of length n

ry

Vector of missing data pattern (FALSE -- missing, TRUE -- observed)

x

Matrix (n x p) of complete covariates.

synthpop_fun

Synthesizing method in the synthpop package

synthpop_args

Function arguments of syn_fun

proper

Logical value specifying whether proper synthesis should be conducted.
