Handling of missing values in statistical software packages for windows

The problem of estimating parameters of distributions by an
incomplete data set is theoretically considered, but in practice
the implementation of the developed methods in commercial
statistical software packages varies from program to program. None
of the examined software offers all possible methods. In some
programs the user has no choice concerning the use of a method, or
no methods at all are available. However, the most popular programs
have not always the largest variety of methods. Hence some work is
still waiting for the producer of statistical software.
