mice.impute.sample: Imputation by simple random sampling

In mice: Multivariate Imputation by Chained Equations

Imputation by simple random sampling

Description

Imputes a random sample from the observed y data

Usage

mice.impute.sample(y, ry, x = NULL, wy = NULL, ...)

Arguments

y	Vector to be imputed
ry	Logical vector of length length(y) indicating the the subset y[ry] of elements in y to which the imputation model is fitted. The ry generally distinguishes the observed (TRUE) and missing values (FALSE) in y.
x	Numeric design matrix with length(y) rows with predictors for y. Matrix x may have no missing values.
wy	Logical vector of length length(y). A TRUE value indicates locations in y for which imputations are created.
...	Other named arguments.

Details

This function takes a simple random sample from the observed values in y, and returns these as imputations.

Value

Vector with imputed data, same type as y, and of length sum(wy)
