SPSS® 12.0 Command Syntax Reference

TRIPLOT(varlist(varlist))(n)
CATPCA 203
A plot of object points, component loadings for variables with an
optimal scaling level that results in line quantification (that is,
SPORD, SPNOM, ORDI, NOMI, and NUME), and centroids for variables
with optimal scaling level MNOM. Following the keyword, a list of
variables in parentheses can be given to indicate the variables to
include in the plot. If the variable list is omitted, all variables are
included. The varlist can contain a second varlist in parentheses to
indicate that triplots with objects labeled with the categories of the
variables in this variable list should be produced (one plot for each
variable). If this second variable list is omitted, a plot with objects
labeled with case numbers is produced. When NORMALIZATION =
INDEPENDENT, this plot is incorrect and therefore not available.
JOINTCAT(varlist)(n) Joint plot of the category points for the variables in the varlist. If no
varlist is given, the category points for all variables are displayed.
PROJCENTR(varname, varlist)(n)
Plot of the centroids of a variable projected on each of the variables
in the varlist. You cannot project centroids of a variable on variables
with MNOM optimal scaling; thus, a variable that has MNOM optimal
scaling can be specified as the variable to be projected but not in the
list of variables to be projected on. When this plot is requested, a table
with the coordinates of the projected centroids is also displayed.
NONE No plots.
BIPLOT Keyword
BIPLOT takes the following keywords:
LOADING(varlist) Object points and component loadings.
CENTR(varlist) Object points and centroids.
For all of the keywords except TRANS and NONE, the user can specify an optional parameter
in order to control the global upper boundary of variable/category label lengths in the plot.
Note that this boundary is applied uniformly to all variables in the list.
The variable/category label-length parameter can take any non-negative integer less than
or equal to 20. The default length is 20. If the length is set to 0, names/values instead of
variable/value labels are displayed to indicate variables/categories. If the specified length is
greater than 20, the procedure simply resets it to 20.
When variables/values do not have labels, then the names/values themselves are used as
the labels.
