SPSS® 12.0 Command Syntax Reference

1022 MULT RESPONSE
• The group names and labels exist only during MULT RESPONSE and disappear once MULT
RESPONSE has been executed. If group names are referred to in other procedures, an
error results.
• For a multiple-dichotomy group, the category labels come from the variable labels
defined for the component variables.
• For a multiple-response group, the category labels come from the value labels for the first
component variable in the group. If categories are missing for the first variable but are
present for other variables in the group, you must define value labels for the missing categories.
(You can use the ADD VALUE LABELS command to define extra value labels.)
Example
MULT RESPONSE GROUPS=MAGS ’MAGAZINES READ’ (TIME TO STONE (2))
/FREQUENCIES=MAGS.
• The GROUPS subcommand creates a multiple-dichotomy group named MAGS. The
variables between and including TIME and STONE become categories of MAGS, and the
frequencies are cases with the value 2 (indicating yes, read the magazine) for the component
variables.
• The group label is MAGAZINES READ.
Example
MULT RESPONSE GROUPS=PROBS ’PERCEIVED NATIONAL PROBLEMS’
(PROB1 TO PROB3 (1,9))
/FREQUENCIES=PROBS.
• The GROUPS subcommand creates the multiple-response group PROBS. The component
variables are the existing variables between and including PROB1 and PROB3, and the
frequencies are tabulated for the values 1 through 9.
• The frequency for a given value is the number of cases that have that value in any of the
variables PROB1 to PROB3.
VARIABLES Subcommand
VARIABLES specifies existing variables to be used in frequency tables and crosstabulations.
Each variable is followed by parentheses enclosing a minimum and a maximum value, which
are used to allocate cells for the tables for that variable.
• You can specify any numeric variable on VARIABLES, but non-integer values are truncated.
• If GROUPS is also specified, VARIABLES follows GROUPS.
• To provide the same minimum and maximum for each of a set of variables, specify a variable
list followed by a range specification.
• The component variables specified on GROUPS can be used in frequency tables and
crosstabulations, but you must specify them again on VARIABLES, along with a range for
the values. You do not have to respecify the component variables if they will not be used
as individual variables in any tables.
