The DESCRIPTIVES procedure reads the active dataset and outputs
descriptive
statistics requested by the user. In addition, it can optionally
compute Z-scores.
The VARIABLES subcommand, which is required, specifies the list of
variables to be analyzed. Keyword VARIABLES is optional.
All other subcommands are optional:
The MISSING subcommand determines the handling of missing variables. If
INCLUDE is set, then user-missing values are included in the
calculations. If NOINCLUDE is set, which is the default, user-missing
values are excluded. If VARIABLE is set, then missing values are
excluded on a variable by variable basis; if LISTWISE is set, then
the entire case is excluded whenever any value in that case has a
system-missing or, if INCLUDE is set, user-missing value.
The FORMAT subcommand affects the output format. Currently the
LABELS/NOLABELS and NOINDEX/INDEX settings are not used.
When SERIAL is
set, both valid and missing number of cases are listed in the output;
when NOSERIAL is set, only valid cases are listed.
The SAVE subcommand causes DESCRIPTIVES to calculate Z scores for all
the specified variables. The Z scores are saved to new variables.
Variable names are generated by trying first the original variable name
with Z prepended and truncated to a maximum of 8 characters, then the
names ZSC000 through ZSC999, STDZ00 through STDZ09, ZZZZ00 through
ZZZZ09, ZQZQ00 through ZQZQ09, in that sequence. In addition, Z score
variable names can be specified explicitly on VARIABLES in the variable
list by enclosing them in parentheses after each variable.
The STATISTICS subcommand specifies the statistics to be displayed:

of the possible values should be self-explanatory. NAME causes the
statistics to be sorted by name. By default, the statistics are listed
in the order that they are specified on the VARIABLES subcommand.
The A and D settings request an ascending or descending
sort order, respectively.
