Example<br />

OVERALS 1177<br />

as a valid category, use the AUTORECODE or RECODE command to recode the values<br />

of that variable.<br />

• OVERALS ignores user-missing value specifications. Positive user-missing values less<br />

than the maximum value specified on the VARIABLES subcommand are treated as valid<br />

category values and are included in the analysis. If you do not want the category included,<br />

use COMPUTE or RECODE to change the value to something outside of the valid range.<br />

Values outside of the range (less than 1 or greater than the maximum value) are treated<br />

as system-missing and are excluded from the analysis.<br />

• If one variable in a set has missing data, all variables in that set are missing for that object<br />

(case).<br />

• Each set must have at least three valid (nonmissing, non-empty) cases.<br />

OVERALS VARIABLES=PRETEST1 PRETEST2 POSTEST1 POSTEST2(20)<br />

SES(5) SCHOOL(3)<br />

/ANALYSIS=PRETEST1 TO POSTEST2 (NUME) SES (ORDI) SCHOOL (SNOM)<br />

/SETS=3(2,2,2)<br />

/PRINT=OBJECT FIT<br />

/PLOT=QUANT(PRETEST1 TO SCHOOL).<br />

• VARIABLES defines the variables and their maximum values.<br />

• ANALYSIS specifies that all of the variables from PRETEST1 to POSTEST2 are to be<br />

analyzed at the numeric level of optimal scaling, SES at the ordinal level, and SCHOOL<br />

as a single nominal. These are all of the variables that will be used in the analysis.<br />

• SETS specifies that there are three sets of variables to be analyzed and two variables in<br />

each set.<br />

• PRINT lists the object and fit scores.<br />

• PLOT plots the single- and multiple-category coordinates of all of the variables in the<br />

analysis.<br />

VARIABLES Subcommand<br />

ANALYSIS Subcommand<br />

VARIABLES specifies all of the variables in the current OVERALS procedure.<br />

• The VARIABLES subcommand is required and precedes all other subcommands. The<br />

actual word VARIABLES can be omitted.<br />

• Each variable or variable list is followed by the maximum value in parentheses.<br />

ANALYSIS specifies the variables to be used in the analysis and the optimal scaling level at<br />

which each variable is to be analyzed.<br />

• The ANALYSIS subcommand is required and follows the VARIABLES subcommand.<br />

• The specification on ANALYSIS is a variable list and an optional keyword in parentheses<br />

indicating the level of optimal scaling.
