DIMENSION Subcommand (ANACOR command)

DIMENSION specifies the number of dimensions you want ANACOR to compute.

• If you do not specify the DIMENSION subcommand, ANACOR computes two dimensions.
• DIMENSION is followed by an integer indicating the number of dimensions.
• In general, you should choose as few dimensions as needed to explain most of the variation. The minimum number of dimensions that can be specified is 1. The maximum number of dimensions that can be specified is equal to the number of levels of the variable with the least number of levels, minus 1. For example, in a table where one variable has five levels and the other has four levels, the maximum number of dimensions that can be specified is (4 – 1), or 3. Empty categories (categories with no data, all zeros, or all missing data) are not counted toward the number of levels of a variable.
• If more than the maximum allowed number of dimensions is specified, ANACOR reduces the number of dimensions to the maximum.
