.SH DESCRIPTION
Sample statistics. Compute mean, standard deviation, skewness, kurtosis,
average deviation, minimum, maximum, median (if option \fB\-m\fR is specified)
and number of valid observations. Option \fB\-O\fR allows one to select specific
statistics. With option \fB\-t\fR statistics are printed for each column of data
