Measurement for Inland Waterway Traffic Analysis Earlier, when we calculated the range, the interquartile deviation, and average absolute deviation, the answers were expressed in the same units as the data itself. 航道交通流分析中统计时间单位的选定当我们计算极差,四分点离差和平均绝对偏差时,答案的计量单位与数据单位量相同的。
Secondly the mean, the standard deviation, the range interquartile and the entropy value of drilling signals are served as process features. 然后分别提取出各信号阶段的信号均值、信号标准差、信号四分位间距和信号熵值作为信号过程特征。
