the entire case is excluded whenever any value in that case has a
system-missing or, if @subcmd{INCLUDE} is set, user-missing value.
-The @subcmd{FORMAT} subcommand affects the output format. Currently the
-@subcmd{LABELS/NOLABELS} and @subcmd{NOINDEX/INDEX} settings are not used.
-When @subcmd{SERIAL} is
-set, both valid and missing number of cases are listed in the output;
-when @subcmd{NOSERIAL} is set, only valid cases are listed.
+The @subcmd{FORMAT} subcommand has no effect. It is accepted for
+backward compatibility.
The @subcmd{SAVE} subcommand causes @cmd{DESCRIPTIVES} to calculate Z scores for all
the specified variables. The Z scores are saved to new variables.

tables and statistics. When set to @subcmd{REPORT}, which is allowed only in
integer mode, user-missing values are included in tables but marked with
-an @samp{M} (for ``missing'') and excluded from statistical
-calculations.

Currently the @subcmd{WRITE} subcommand is ignored.

If specified, @subcmd{MATRIX IN} must be followed by @samp{COV} or @samp{CORR},
then by @samp{=} and @var{file_spec} all in parentheses.
@var{file_spec} may either be an asterisk, which indicates the currently loaded

+dataset, or it may be a filename to be loaded. @xref{MATRIX DATA}, for the expected
format of the file.
The @subcmd{/EXTRACTION} subcommand is used to specify the way in which factors (components) are extracted from the data.
The covariance matrix is printed.
@item @subcmd{DET}
The determinant of the correlation or covariance matrix is printed.
+@item @subcmd{AIC}
+ The anti-image covariance and anti-image correlation matrices are printed.
@item @subcmd{KMO}
The Kaiser-Meyer-Olkin measure of sampling adequacy and the Bartlett test of sphericity is printed.
