SPSS® 12.0 Command Syntax Reference

ACTIVE Keyword
The ACTIVE keyword has the following keywords:
CATPCA 197
MODEIMPU Impute missing values on a variable with the most frequent category (mode).
When there are multiple modes, the smallest category indicator is used.
MODEIMPU is the default.
EXTRACAT Impute missing values on a variable with an extra category indicator. This
implies that objects with a missing value are considered to belong to the
same (extra) category.
Note that with active treatment of missing values, imputation is done before the analysis
starts and thus will affect the quantification and the solution.
SUPPLEMENTARY Subcommand
The SUPPLEMENTARY subcommand specifies the objects and/or variables that you want to
treat as supplementary. Supplementary variables must be found in the ANALYSIS
subcommand. You cannot weight supplementary objects and variables (specified weights are
ignored). For supplementary variables, all options on the MISSING subcommand can be
specified except LISTWISE.
• The SUPPLEMENTARY subcommand is ignored when CONFIGURATION=FIXED.
OBJECT Objects you want to treat as supplementary are indicated with an object
number list in parentheses following OBJECT. The keyword TO is allowed.
VARIABLE Variables you want to treat as supplementary are indicated with a variable
list in parentheses following VARIABLE. The keyword TO is allowed and honors
the order of variables in the VARIABLES subcommand.
CONFIGURATION Subcommand
The CONFIGURATION subcommand allows you to read data from a file containing the coordinates
of a configuration. The first variable in this file should contain the coordinates for the
first dimension, the second variable should contain the coordinates for the second dimension,
and so forth.
INITIAL(file) Use configuration in the external file as the starting point of the analysis.
FIXED(file) Fit objects and variables in the fixed configuration found in the external file.
The variables to fit in should be specified on the ANALYSIS subcommand but
will be treated as supplementary. The SUPPLEMENTARY subcommand and
variable weights are ignored.
