| Abstract: | The basic algorithm of GMDH (group method of data handling)method was introduced The modified GMDH method was applied to Na gara River,Japan to construct the DO and COD predicting models The models were reasonable,with the correlation coefficient as high as 0 96 The varying regul arity of the two parameters were analyzed briefly |
