标题: 如何根据二次判别函数确定判别准则
我的一个判别分析的输出结果部分如下：
         The DISCRIM Procedure

                     Pooled Within-Class Covariance Matrix,    DF = 44

                        Variable             x1             x2

                        x1          0.0456942684    0.0176823896
                        x2          0.0176823896    0.0109280260

                              Within Covariance Matrix Information

                                                   Natural Log of the
                                    Covariance Determinant of the
                           group Matrix Rank    Covariance Matrix

                              0             2             -9.06480
                              1             2          -10.04483
  The DISCRIM Procedure

                     Pairwise Generalized Squared Distances Between Groups

                        2       _ _    -1  _ _
                        D (i|j) = (X - X )' COV (X - X ) + ln |COV |
                                    i j    j i j          j

                              Generalized Squared Distance to group

                           From group          0          1

                                    0    -9.06480    -0.84975
                                    1    -5.69398    -10.04483
怎样根据以上信息建立判别准则。
