Chamont Wang Ph.D., in Handbook of Statistical Analysis and Data Mining Applications, 2009. Decision Matrix and the Profit Charts. Almost all data mining packages are confused by the subtle difference between a misclassification matrix and a decision matrix.SAS-EM is a rare exception. Note that the first matrix does not allow nonzero entries on the diagonal line, while the second matrix is.
