Imputation of univariate missing data using a Bayesian logistic mixed model based on non-informative prior distributions

Description

Imputes univariate missing data using a Bayesian logistic mixed model based on non-informative prior distributions. The method is dedicated to a binary outcome stratified in severals clusters. Should be used with few clusters and few individuals per cluster. Can be very slow to perform otherwise.

Usage

mice.impute.2l.glm.bin(y, ry, x, type, ...)

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.
`type`	Vector of length `ncol(x)` identifying random and class variables. Random variables are identified by a '2'. The class variable (only one is allowed) is coded as '-2'. Random variables also include the fixed effect.
`...`	Other named arguments.

Details

Imputes univariate missing data using a Bayesian logistic mixed model based on non-informative prior distributions. The variability on the parameters of the imputation is propagated according to an explicit Bayesian modelling. More precisely, improper prior distributions are used for regression coefficients and covariance matrix of random effects. The method is recommended for datasets with a small number of clusters and a small number of individuals per cluster. Otherwise, the method can be very slow to perform.

Value

A vector of length nmis with imputations.
