SPSS® 12.0 Command Syntax Reference

Example
HOMALS 729
Values outside of the range (less than 1 or greater than the maximum value) are treated as
system-missing and are excluded from the analysis.
HOMALS VARIABLES=ACOLA(2) BCOLA(2) CCOLA(2) DCOLA(2)
/PRINT=FREQ EIGEN QUANT OBJECT.
• The four variables are analyzed using all available observations. Each variable has two
categories, 1 and 2.
• The PRINT subcommand lists the frequencies, eigenvalues, category quantifications, and
object scores.
• By default, plots of the category quantifications and the object scores are produced.
VARIABLES Subcommand
VARIABLES specifies the variables that will be used in the analysis.
• The VARIABLES subcommand is required. The actual word VARIABLES can be omitted.
• After each variable or variable list, specify in parentheses the maximum number of categories
(levels) of the variables.
• The number specified in parentheses indicates the number of categories and the maximum
category value. For example, VAR1(3) indicates that VAR1 has three categories coded 1, 2,
and 3. However, if a variable is not coded with consecutive integers, the number of categories
used in the analysis will differ from the number of observed categories. For
example, if a three-category variable is coded {2, 4, 6}, the maximum category value is 6.
The analysis treats the variable as having six categories, three of which (categories 1, 3,
and 5) are not observed and receive quantifications of 0.
• To avoid unnecessary output, use the AUTORECODE or RECODE command before
HOMALS to recode a variable that does not have sequential values (see the SPSS Syntax
Reference Guide for more information on AUTORECODE and RECODE).
Example
DATA LIST FREE/V1 V2 V3.
BEGIN DATA
3 1 1
6 1 1
3 1 3
3 2 2
3 2 2
6 2 2
6 1 3
6 2 2
3 2 2
6 2 1
END DATA.
AUTORECODE V1 /INTO NEWVAR1.
HOMALS VARIABLES=NEWVAR1 V2(2) V3(3).
• DATA LIST defines three variables, V1, V2, and V3.
