If the values of these parameters were known , ade- quate discriminant functions based on them could be directly specified . ... estimates of the parameter values , and the discriminant functions are then determined by these estimates .

We assume that the p ( Xi ) are known functions of a finite number of characteristic parameters whose values we might not know a priori . For example , we may know that the p ( X | i ) , i = 1 , . . . , R , are normal probability ...

values are given by 9i ( 1 Wi = log Pi ( 1 Wa + 1 = log [ 1 p ( 1 ) - - Ji ) pi ) i = 1 , 5 ] + log — p ( 1 ) ... Note , for example , that the values of the a priori proba- bilities p ( 1 ) and 1 p ( 1 ) affect only the value of wa + 1 .
