The nonparametric test are not as efficient or "sharp" as parametric test . 非參數(shù)檢驗不如參數(shù)檢驗那么靈敏有效。

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,額外的測試存取機構(gòu)也帶來額外的時間延遲而造成測式時間參數(shù)上的困難以及準確度。
Viscoelastic stochastic fem can not only calculate reliability index , but also determine the accuracy requirement for parametric testing according to given reliability 粘彈性隨機有限元方法既可以提供可靠度指標,又能夠根據(jù)給定可靠度或安全系數(shù)對參數(shù)的測試精度提出要求。
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 綜合運用聚類分析和非參數(shù)檢驗的方法,結(jié)合傳統(tǒng)的統(tǒng)計過程控制手段,提出了適用于多品種、大批量的高度自動化機械制造過程控制框架。
