SPSS® 12.0 Command Syntax Reference

OUTFILE Subcommand
ALSCAL 111
OUTFILE saves coordinate and weight matrices to an SPSS data file. The only specification
is a name for the output file.
• The output data file has an alphanumeric (short string) variable named TYPE_ that identifies
the kind of values in each row, a numeric variable DIMENS that specifies the number
of dimensions, a numeric variable MATNUM that indicates the subject (matrix) to which
each set of coordinates corresponds, and variables DIM1, DIM2,...DIMn that correspond to
the n dimensions in the model.
• The values of any split-file variables are also included in the output file.
• The file created by OUTFILE can be used by subsequent ALSCAL commands as initial data.
The following are the types of configurations and weights that can be included in the output
file:
CONFIG Stimulus configuration coordinates.
ROWCONF Row stimulus configuration coordinates.
COLCONF Column stimulus configuration coordinates.
SUBJWGHT Subject (matrix) weights.
FLATWGHT Flattened subject (matrix) weights.
GEMWGHT Generalized weights.
STIMWGHT Stimulus weights.
Only the first three characters of each identifier are written to variable TYPE_ in the file. For
example, CONFIG becomes CON. The structure of the file is determined by the SHAPE and
MODEL subcommands, as shown in Table 2.
