【摘要】 漏失数据的弥补,通常采用使误差项的平方和达到最小的原则来确定,这样弥补的数据,有时会出现负值等异常情况.本文提出采用相邻小区的平均值来代替漏失数据,或用回归分析的方法分析试验结果,同样能得到最小二乘法相一致的结论,但不会出现负值.更多还原

【Abstract】 Redeeming of leak data is usually confirmed by using the principle of making the square sum of error terms to reach least. But he redeeming data by this method sometimes appear some abnormal phenomena such as negative values. In this paper, by using the average value of border small sections to replace the leak data or using the method of regression analysis to analysis the experimental results, we can obtain the accordant conclusion that is obtained by using method of minimum square. Further more using the two methods will not appear negative values.更多还原
