SPSS® 12.0 Command Syntax Reference

Operations
MULT RESPONSE 1021
• Empty categories are not displayed in either frequency tables or crosstabulations.
• If you define a multiple-response group with a very wide range, the tables require substantial
amounts of workspace. If the component variables are sparsely distributed, you
should recode them to minimize the workspace required.
• MULT RESPONSE stores category labels in the workspace. If there is insufficient space to
store the labels after the tables are built, the labels are not displayed.
Limitations
• The component variables must have integer values. Non-integer values are truncated.
• Maximum 100 existing variables named or implied by GROUPS and VARIABLES together.
• Maximum 20 groups defined on GROUPS.
• Maximum 32,767 categories for a multiple-response group or an individual variable.
• Maximum 10 table lists on TABLES.
• Maximum 5 dimensions per table.
• Maximum 100 groups and variables named or implied on FREQUENCIES and TABLES
together.
• Maximum 200 non-empty rows and 200 non-empty columns in a single table.
GROUPS Subcommand
GROUPS defines both multiple-dichotomy and multiple-response groups.
• Specify a name for the group and an optional label, followed by a list of the component
variables and the value or values to be used in the tabulation.
• Enclose the variable list in parentheses and enclose the values in an inner set of parentheses
following the last variable in the list.
• The label for the group is optional and can be up to 40 characters in length, including
imbedded blanks. Apostrophes or quotes around the label are not required.
• To define a multiple-dichotomy group, specify only one tabulating value (the value that
represents yes) following the variable list. Each component variable becomes a value of
the group variable, and the number of cases that have the tabulating value becomes the
frequency. If there are no cases with the tabulating value for a given component variable,
that variable does not appear in the tabulation.
• To define a multiple-response group, specify two values following the variable list. These
are the minimum and maximum values of the component variables. The group variable
will have the same range of values. The frequency for each value is tabulated across all
component variables in the list.
• You can use any valid variable name for the group except the name of an existing variable
specified on the same MULT RESPONSE command. However, you can reuse a group name
on another MULT RESPONSE command.
