SUPPLEMENTARY Subcommand (CATREG command)

The SUPPLEMENTARY subcommand specifies the objects that you want to treat as supplementary. You cannot weight supplementary objects (specified weights are ignored). This subcommand can be used to specify test cases.

OBJECT. Supplementary objects. Objects that you want to treat as supplementary are indicated with an object number list in parentheses following OBJECT. The keyword TO is allowed—for example, OBJECT(1 TO 1 3 5 TO 9).

• Supplementary object are exluced from the analysis. The quantifications resulting from the analysis for the active objects are applied to the categories of supplementary objects, and predicted and residual values for supplementary objects are provided.
• If a supplementary object has a category that does not occur in the active data, the following strategies are applied:

  If the variable on which the non-occuring category occurs has a numeric or spline scaling level, and the non-occuring category lies within the range of categories in the active data, then interpolation is applied.

  If the variable has numeric scaling level and the non-occuring category lies outside the range of categories in the active data, then extrapolation is applied.

  Otherwise the case is excluded.

• Excluded cases are represented by a dot (the sysmis symbol) on every saved variable.
