The nonparametric test are not as efficient or "sharp" as parametric test . 非参数检验不如参数检验那么灵敏有效。

Furthermore , the required general test access mechanism usually introduces extra timing penalties for parametric testing , and hence reduces the accuracy of ac measurement 除此之外,额外的测试存取机构也带来额外的时间延迟而造成测式时间参数上的困难以及准确度。
Viscoelastic stochastic fem can not only calculate reliability index , but also determine the accuracy requirement for parametric testing according to given reliability 粘弹性随机有限元方法既可以提供可靠度指标,又能够根据给定可靠度或安全系数对参数的测试精度提出要求。
By synthetically applying the method of cluster analysts and of parametric test and combining with the traditional means of statistical process control , a highly automatic controlling frame suitable for multi - variety and large quantity machine building process was pot forward 综合运用聚类分析和非参数检验的方法,结合传统的统计过程控制手段,提出了适用于多品种、大批量的高度自动化机械制造过程控制框架。
It puts up quantitative analysis on the otherness of area structure in highway investment by means of anova analysis and rank test of non - parametric test in order to find out whether the extent of the otherness change . by means of cluster analysis chapter two demonstrates on the capital source structure of highway investment from 1991 in order to reflect on the change of capital source structure 运用方差分析与非参数检验中的秩和检验对公路投资的区域结构的差异性进行了定量分析,以找出近年来公路投资的区域性差异程度是否有所变化;运用多元统计分析中的聚类分析对1991年以来公路投资的资金来源结构进行了实证分析,以反映资金来源结构的变动状况。
All algorithms are developed with visual basic and c . in the present paper a report is given of the results obtained the tests of independence , correlation and randomness which are involved parametric test , chi ~ square test , k ~ s test , correlation coefficient test , contingency table test and runs test 作者对产生的随机数进行了大量的检验工作。其中包括独立性、相关性、随机性的检验,涉及参数检验、卡方检验、 k - s检验、相关系数检验、列联表检验、游程检验等多种方法和形式。
