-
VARIABLES
defines
variables. The keyword TO
refers
to the order of the variables in the working data file.
- The
ANALYSIS
subcommand defines variables used in the analysis. It is specified
that TEST1 and TEST2 have a weight of 2 (for the other variables, WEIGHT
is not specified and thus they have
the default weight value of 1).
-
DISCRETIZATION
specifies that TEST6 and TEST8, which are fractional value variables,
are discretized: TEST6 by recoding
into seven categories with a normal distribution (default because
unspecified) and TEST8 by “multiplying”. TEST1, which is a categorical variable, is
recoded into five categories with a close to uniform distribution.
-
MISSING
specifies
that objects with missing values on TEST5 and TEST6 are included in the
analysis: missing values on TEST5 are replaced with the mode (default if not specified) and missing
values on TEST6 are treated as
an extra category. Objects with a missing value on TEST8 are excluded from the analysis. For all other variables,
the default is in effect; that is, missing values (not objects) are
excluded from the analysis.
-
CONFIGURATION
specifies iniconf.sav as the
file containing the coordinates of a configuration that is to be
used as the initial configuration (default because unspecified).
-
DIMENSION
specifies
the number of dimensions to be 2. This is the default, so this subcommand
could be omitted here.
- The
NORMALIZATION
subcommand specifies optimization of the association between variables.
This is the default, so this subcommand could be omitted here.
-
MAXITER
specifies
the maximum number of iterations to be 150 instead of the default
value of 100.
-
CRITITER
sets
the convergence criterion to a value smaller than the default value.
-
PRINT
specifies
descriptives, discrimination measures, and correlations (all default),
and quantifications for TEST1 to TEST3, and the object scores.
-
PLOT
is used
to request transformation plots for the variables TEST2 to TEST5, an
object points plot labeled with the categories of TEST2, and an object points plot labeled with the categories
of TEST3.
- The
SAVE
subcommand
adds the transformed variables and the object scores to the working
data file.
- The
OUTFILE
subcommand
writes the transformed data to a data file called trans.sav and the object scores to a data file called obs.sav, both in the directory /data.
