通过考察厚近薄远原则所选用的公式F ,可以看出G取值是非常关键的。改变H值可以改变厚近薄远的程度,决定不同时期历史数据的模型误差对预测结果的影响。I 值非常小时,将会使较远的模型误差对最终预测结果的影响几乎为零;J 取值越大,其优选的结果越来越靠近于采用远近相同原则的优选结果,换句话说,K 取值越大,厚近薄远的效果越弱。

It could be viewed, through study on Formula F selected by the principel as "giving more weight on the closer one rather than the further", that it is very important as of G value. Change in H value may alter degree/extent(任选) of “weighing more on the closer one than the further”, which does determine impacts of model errors of history datum during periods on predictions. Extremely small I value may lead to impact nearly to zero as of "the further weighing" model error laid on final predictions, while the larger J value gets, the closer the results with optimum seeking method are to that drawn from the principle of "equality between the closer one and the further"; in other words(或:that is,namely), the larger J value gets, the weaker effect as of "weighing more on the closer one than the further" it produces.

Pass to investigate thick near thin far principle choose of formula F, can see a G's taking a value is very decisive.Changing the H value can change thick near thin far degree, decide the model error margin of corresponding period history data not to the influence that predicts a result.The I is very worth a hour, will make the influence of the farther model error margin upon the end estimate result almost to zero;The J takes a value more big, the result of its optimization more and more close to in adoption far near same principle of optimization result, in other words, the K takes to be worth more big, thick near thin far of the effect is more weak.

By investigating the thick BoYuan principle for the use of nearly formula, it can be seen that the G F values are very key change H value can change near the extent of the BoYuan thick, decided to different period of historical data model for prediction error influence on the result of the I value very hour, will make far away on final prediction model error influence on the result of the almost to zero; The greater the value, the J
