EQUAL Subcommand (CORRESPONDENCE command)

The EQUAL subcommand specifies the rows and/or columns that you want to restrict to have equal scores.

  • For casewise data, the specification on EQUAL is the row and/or column variable name, followed by a list of at least two values in parentheses. The values must be in the value range specified on the TABLE subcommand for the row or column variable.
  • For table data, the specification on EQUAL is ROW and/or COLUMN, followed by a value list in parentheses. The values represent the row or column indices of the table input data.
  • Rows or columns that are restricted to have equal scores cannot be supplementary.
  • The maximum number of equal rows or columns is the number of active rows or columns minus 1.

Example

CORRESPONDENCE TABLE=MENTAL(1,8) BY SES(1,6)
/EQUAL MENTAL(1,2) (6,7) SES(1,2,3).
  • EQUAL specifies the first and second level of MENTAL, the sixth and seventh level of MENTAL, and the first, second, and third levels of SES to have equal scores.
