比较群体之间的差异是生物学家经常面临的任务，例如在生态田间试验或处理宏基因组学数据时。然而，研究人员经常在选择哪种多样性衡量标准上摇摆不定，因为有多种方法可用。正如Jost（2008，Molecular Ecology，17，4015）所指出的那样，广泛使用的指标，如香农或辛普森指数具有令人不快的特性，这使得它们难以比较和解释。许多与使用这些“原始”指数相关的问题可以通过将其转化为“真正的”多样性措施来纠正。我们引入了一种技术，允许比较两组或多组观测值，并同时测试用户定义的一些“真正的”多样性度量的选择。该程序根据Westfall和Young的方法（1993年，基于呼吸的多重检验：p值调整的示例和方法，49，941）产生多重调整的P值，该方法确保当组和/或多样性指数的数量增加时，假阳性率（I型错误）不会增加。软件在R软件包“simboot”中提供。
Comparing diversities between groups is a task biologists are frequently faced with, for example in ecological field trials or when dealing with metagenomics data. However, researchers often waver about which measure of diversity to choose as there is a multitude of approaches available. As Jost (2008,Molecular Ecology,17, 4015) has pointed out, widely used measures such as the Shannon or Simpson index have undesirable properties which make them hard to compare and interpret. Many of the problems associated with the use of these ‘raw’ indices can be corrected by transforming them into ‘true’ diversity measures. We introduce a technique that allows the comparison of two or more groups of observations and simultaneously tests a user‐defined selection of a number of ‘true’ diversity measures. This procedure yields multiplicity‐adjustedP‐values according to the method of Westfall and Young (1993,Resampling‐Based Multiple Testing: Examples and Methods for p‐Value Adjustment, 49, 941), which ensures that the rate of false positives (type I error) does not rise when the number of groups and/or diversity indices is extended. Software is available in the R package ‘simboot’.
