CRITERIA Subcommand (TWOSTEP CLUSTER command)

The CRITERIA subcommand specifies the following settings for the clustering algorithm:

INITTHRESHOLD. The initial threshold used to grow the CF tree. The default is 0. If inserting a specific case into a leaf of the CF tree would yield tightness less than the threshold, the leaf is not split. If the tightness exceeds the threshold, the leaf is split.

MXBRANCH. The maximum number of child nodes that a leaf node can have. The default is 8.

MXLEVEL. The maximum number of levels that the CF tree can have. The default is 3.
