| Abstract: | Parameters of a six -order autoregressive model were calculated , which were the sum of minimum mean square error (e0) and AR parameters from al to a6 for analysis of auditory brainstem responses (ABR) of 20 normal and 14 ictrocochlear lesion ears e0, a3 and a6 were parameters of the bigger contribution of variance, obtained by the method of stepwise regression analysis and stepwise discriminatory analysis was separatdy made according to Bayes criterion and Fisher criterion . The discriminating Junctions were Y1 =0.8047 x1 -2.8044 x2 -3.9784 , and Y2 =0.1198 X1+1.7669 x2-1.7236,The rate of discriminative error was 29% (1/34) .The results demonstrated the probability of auto - diagnosis of ABR by this method . |
