In this paper , the calculating method of the process capability index for non - normal distribution is given by pearson system of distributions 摘要本文利用皮尔逊分布族设计了一种计算非正态分布工序能力的方法。
Tolerances for building - recommendations for statistical basis for predicting fit between components having a normal distribution of sizes 建筑用公差.第2部分:具有正态尺寸分布部件之间预配合的统计基础推荐标准
When the data is not in normal or logarithmic normal distribution , the least - squared method is not applicable to obtaining the sensitive index 若试验数据为非正态或非对数正态分布,最小二乘法求优会受到限制。
Generally , the calculation of semi - variogram calls for data to conform to normal distribution , or it will cause proportion effects 变异函数的计算一般要求数据符合正态分布,否则可能会使变异函数产生比例效应。
The distribution patterns of total phosphate , available phosphate , available iron follow lognormal and others normal distribution . 3 在分布类型上,除全磷、速效磷、有效铁服从对数正态分布外,其余全为正态分布。
