+The STATISTICS subcommand requests additional statistics to be displayed.  The keyword 
+DESCRIPTIVES requests that the mean, number of non-missing cases, and the non-biased
+estimator of the standard deviation are displayed.
+These statistics will be displayed in a separated table, for all the variables listed
+in any /VARIABLES subcommand.
+The XPROD keyword requests cross-product deviations and covariance estimators to 
+be displayed for each pair of variables.
+The keyword ALL is the union of DESCRIPTIVES and XPROD.
