Arguments

dat	Numeric data frame

Value

A list with following entries

nobs	List with number of observations for each missing response pattern
M	List with mean vectors
S	List with covariance matrices
varindex	List with indices of observed variables
NP	Number of missing data patterns
N	Total sample size
