The celebrated Gini(-Simpson) biodiversity index has found very useful applications in ecology, bio-environmetrics, econometry, psychometry, genetics, and lately in bioinformatics as well. In econommic, social and environmental sciences, there are some ordinal categorical variables or grouped data sets...

A detail in the result in Table 2 is that it in some sense illustrates Simpson's paradox in the following way. While the vocational group as a whole has a fairly equal gender distribution, this is not the case when looking at one study programme at the time. Student heterogeneity at...
①多样性视角,根据不同用地类型、功能的面积比例直接计算混合度,或借助辛普森指数(Simpson index)、香农—威纳指数(Shannon-Weaver index)、熵指数(Entropy Index)、碎化指数(Fragmentation Index)、分异指数(Dissimilarity Index)等多样性指标计算混合度。②可达性视角,从不同用地、功能的空间使用需求着手,计算之间的...
For researching complexity measures from the view of entropy, we propose a new permutation entropy based on Gini-Simpson index (GPE). Logistic map is applied to simulate time series to show the accuracy of the GPE method, and expound the extreme robustness of our GPE by the results of ...
