ANACOR TABLE=ALL(6,7).<br />

• DATA LIST defines the seven columns of the table as the variables.<br />

• The TABLE=ALL specification indicates that the data are the cells of a table. The (6,7)<br />

specification indicates that there are six rows and seven columns.<br />

DIMENSION Subcommand<br />

DIMENSION specifies the number of dimensions you want ANACOR to compute.<br />

• If you do not specify the DIMENSION subcommand, ANACOR computes two dimensions.<br />

• DIMENSION is followed by an integer indicating the number of dimensions.<br />

• In general, you should choose as few dimensions as needed to explain most of the variation.<br />

The minimum number of dimensions that can be specified is 1. The maximum number<br />

of dimensions that can be specified is equal to the number of levels of the variable with<br />

the least number of levels, minus 1. For example, in a table where one variable has five<br />

levels and the other has four levels, the maximum number of dimensions that can be specified<br />

is (4 – 1), or 3. Empty categories (categories with no data, all zeros, or all missing<br />

data) are not counted toward the number of levels of a variable.<br />

• If more than the maximum allowed number of dimensions is specified, ANACOR reduces<br />

the number of dimensions to the maximum.<br />

NORMALIZATION Subcommand<br />

The NORMALIZATION subcommand specifies one of five methods for normalizing the row<br />

and column scores. Only the scores and variances are affected; contributions and profiles are<br />

not changed.<br />

The following keywords are available:<br />

CANONICAL For each dimension, rows are the weighted average of columns divided by<br />

the matching singular value, and columns are the weighted average of rows<br />

divided by the matching singular value. This is the default if the<br />

NORMALIZATION subcommand is not specified. DEFAULT is an alias for<br />

CANONICAL. Use this normalization method if you are primarily interested<br />

in differences or similarities between variables.<br />

PRINCIPAL Distances between row points and column points are approximations of chisquare<br />

distances. The distances represent the distance between the row or
