mice.impute.logreg.boot: Imputation by logistic regression using the bootstrap

Description

Imputes univariate missing data using logistic regression by a bootstrapped logistic regression model. The bootstrap method draws a simple bootstrap sample with replacement from the observed data y[ry] and x[ry,]. Perfect prediction is handled by the data augmentation method.

Usage

mice.impute.logreg.boot(y, ry, x, ...)

Arguments

y

Incomplete data vector of length n

ry

Vector of missing data pattern of length n (FALSE=missing, TRUE=observed)

x

Matrix (n x p) of complete covariates.

...

Other named arguments.

Value

• A vector of length nmis with imputations (0 or 1).
