SPSS® 12.0 Command Syntax Reference

378 CTABLES
• You can create multiple response sets with the MRSETS command and use them like
ordinary categorical variables in a table expression. You can control the percentage base
by choosing an appropriate summary function, and you can control with the MRSETS subcommand
whether duplicate responses from a single respondent are counted.
• You can assign totals to categorical variables at different nesting levels to create subtable
and table totals, and you can assign subtotals across subsets of the values of a variable.
See the CATEGORIES subcommand.
• You can determine on a per-variable basis which categories to display in the table, including
whether to display missing values and empty categories for which variable labels exist.
You can also sort categories by name, label, or the value of a summary function. See the
CATEGORIES subcommand.
• You can specify whether to show or hide summary and category labels and where to
position the labels. For variable labels, you can specify whether to show labels, names,
both, or neither. See the SLABELS, CLABELS, and VLABELS subcommands.
• You can request chi-square tests and pairwise comparisons of column proportions and
means. See the SIGTEST and COMPARETEST subcommands.
• You can assign custom titles and captions (see the TITLES subcommand) and control what
displays for empty cells and those for which a summary function cannot be computed. See
the FORMAT subcommand.
• CTABLES ignores SPLIT FILE requests if layered splits (compare groups in the graphical
user interface) are requested. You can compare groups by using the split variables at the
highest nesting level for row variables. See the TABLE subcommand for nesting variables.
Syntax Conventions
• The basic specification is a TABLE subcommand with at least one variable in one
dimension. Multiple TABLE subcommands can be included in one CTABLES command.
• The global subcommands FORMAT, VLABELS, MRSETS, and SMISSING must precede the
first TABLE subcommand and can be named in any order.
• The local subcommands SLABELS, CLABELS, CATEGORIES, TITLES, SIGTEST, and
COMPARETEST follow the TABLE subcommand in any order and refer to the immediately
preceding table expression.
• In general, if subcommands are repeated, their specifications are merged. The last value
of each specified attribute is honored.
• Equals signs shown in the syntax charts are required.
• Square brackets shown in the syntax charts are required.
• All keywords except summary function names, attribute values, and explicit category list
keywords can be truncated to as few as three characters. Function names must be spelled
in full.
• The slash before all subcommands, including the first, is required.
