SPSS® 12.0 Command Syntax Reference

202 Syntax Reference
CATEGORY(varlist)(n)
Plots of the category points. Both the centroid coordinates and the line
coordinates are plotted. A list of variables must be given in parentheses
following the keyword. For variables with optimal scaling level
MNOM, categories are in the centroids of the objects. For all other
optimal scaling levels, categories are on a vector through the origin.
LOADING(varlist(CENTR(varlist)))(l)
Plot of the component loadings optionally with centroids. By default,
all variables with an optimal scaling level that results in vector quantification
(that is, SPORD, SPNOM, ORDI, NOMI, and NUME) are
included in this plot. LOADING can be followed by a varlist to select
the loadings to include in the plot. When "LOADING(" or the varlist
following "LOADING(" is followed by the keyword CENTR in parentheses,
centroids are plotted for all variables with optimal scaling level
MNOM. CENTR can be followed by a varlist in parentheses to select
MNOM variables whose centroids are to be included in the plot. When
there is no variable whose optimal scaling level is SPORD, SPNOM,
ORDI, NOMI, or NUME in the analysis, this plot cannot be produced.
TRANS(varlist(n)) Transformation plots (optimal category quantifications against category
indicators). A list of variables must be given in parentheses
following the keyword. MNOM variables in the varlist can be followed
by a number of dimensions in parentheses to indicate that you want to
display p transformation plots, one for each of the first p dimensions.
RESID(varlist(n))(n) Plot of residuals per variable. Following the keyword, a list of variables
in parentheses must be given. A variable with optimal scaling
level MNOM can be followed by a number in parentheses to indicate
the number of dimensions you want a residuals plot for. If the number
of dimensions is not specified, a plot for the first dimension is
produced.
BIPLOT(keyword(varlist))(varlist)(n)
Plot of objects and variables. The coordinates for the variables can
be chosen to be component loading or centroids, using keywords
LOADING and/or CENTR in parentheses following BIPLOT. When no
keyword is given, component loadings are plotted. When
NORMALIZATION = INDEPENDENT, this plot is incorrect and therefore
not available.
Following LOADING and CENTR, a list of variables in parentheses
can be given to indicate the variables to be included in the plot. If
the variable list is omitted, a plot including all variables is produced.
Following BIPLOT, a list of variables in parentheses can be
given to indicate that plots with objects labeled with the categories
of the variables should be produced (one plot for each variable). If
the variable list is omitted, a plot with objects labeled with case
numbers is produced.
