Based on this, we studied the correlation of ordinal data by the use of Kendall statistics, which makes up the shortage that Kappa statistics can make agreement analysis only with the nominal data in attribute measurement system agreement analysis.
本文在此基础上使用Kendall统计量对属性数据中的定序数据进行了相关性研究,弥补了一致性分析的不足之处。
nominal data is the simplest data.
称名数据是最简单的数据。
clustering algorithm of nominal data based on entropy
基于信息熵的标称变量聚类算法研究
The test analysis shows that the fitted slope of test data to nominal stress and hot spot stress S-N curves for aluminum 5083 welded joint with longitudinal fillet welded gusset is 5.62, higher than 3.0 recommended by ⅱ W.
试验分析说明铝合金5083纵向角接板焊接接头名义应力和热点应力疲劳S-N曲线试验数据拟合斜率为5.62,高于国际焊接学会推荐的斜率为3.0;
