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.
When Z scores are calculated, pspp ignores `TEMPORARY`

,
treating temporary transformations as permanent.

The `STATISTICS`

subcommand specifies the statistics to be displayed:

`ALL`

- All of the statistics below.
`MEAN`

- Arithmetic mean.
`SEMEAN`

- Standard error of the mean.
`STDDEV`

- Standard deviation.
`VARIANCE`

- Variance.
`KURTOSIS`

- Kurtosis and standard error of the kurtosis.
`SKEWNESS`

- Skewness and standard error of the skewness.
`RANGE`

- Range.
`MINIMUM`

- Minimum value.
`MAXIMUM`

- Maximum value.
`SUM`

- Sum.
`DEFAULT`

- Mean, standard deviation of the mean, minimum, maximum.
`SEKURTOSIS`

- Standard error of the kurtosis.
`SESKEWNESS`

- Standard error of the skewness.

The `SORT`

subcommand specifies how the statistics should be sorted. Most
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.
