Average Sample Number for Sampling Inspection by Attributes in Acceptance Check 关于计数验收抽样检查中的平均检验件数问题
The one-hundred-time forest stand average breast diameter as the diameter to make circle-shaped sample results that section area of breast height per hectare equals to that the number of the forest timbers inside the circle plus an half of the number of the timbers on the circle boundary. 以林分平均胸高直径的100倍为直径作圆形样地,得出林分每公顷胸高断面积等于圆形样地圆内的林木株数加上圆界上林木株数的一半。
Calculation methods of average sample number ( ASN) were described, and the three methods were discussed through an example. 介绍了平均样本大小(ASN)的计算公式,举例说明了ASN的3种计算方法:直接推导法;
In this paper, calculation of average sample number for the latter is given. 本文给出后者的平均检验件数的计算。
Its robustness including false alarm probability, detection probability and average sample number is demonstrated and its asymptotic performance is discussed. 导出了它的一般结构。推证了它在虚警概率、检测概率和平均抽样个数等方面的坚韧性,并讨论了它的渐近性能。
When the predictive bank number is chosen as the correlation dimension of the system, the average prediction error of the memory-based predictor is small, which also decreases as the sample number increases. 选取系统的关联维数作为预测阶数时,基于记忆库预测方法的平均预测误差较小,且其预测误差随样本容量的增多而减小。
The parameters 'approximate values are ensured by the average value of several estimate, and the sample number is ensured by the variance coefficient. 通过多次估计的均值作为参数的近似值,采样的样本数通过方差系数确定。
