ANALYSIS Subcommand (CATPCA command)

ANALYSIS specifies the variables to be used in the computations, the optimal scaling level, and the variable weight for each variable or variable list. ANALYSIS also specifies supplementary variables and their optimal scaling level. No weight can be specified for supplementary variables.

• At least two variables must be specified, except when the CONFIGURATION subcommand is used with the FIXED keyword.
• All variables on ANALYSIS must be specified on the VARIABLES subcommand.
• The ANALYSIS subcommand is required.
• The keyword TO in the variable list honors the order of variables in the VARIABLES subcommand.
• Optimal scaling levels and variable weights are indicated by the keywords LEVEL and WEIGHT in parentheses following the variable or variable list.

WEIGHT. Specifies the variable weight with a positive integer. The default value is 1. If WEIGHT is specified for supplementary variables, it is ignored, and a syntax warning is issued.

LEVEL. Specifies the optimal scaling level.
