Description Usage Arguments Value Author(s) References See Also Examples

It computes the consistency matrix of a decision table object. A Consistency Matrix object is made of each rule consistency check against the other rules in a Decision Table object. A couple of rules are inconsistent if they have the same conditions and different decision; if they have the same decision they are consistent; if they have different conditions no matter the decision they are consistent.

A Decision Table object

It returns a boolean diagonal matrix indicating inconsistency between rules. It must be interpreted by columns.
