摘要

大多数经典统计检验都假设数据呈正态分布。如果不符合这一假设，研究人员通常会求助于非参数方法。这些方法有一些缺点，如果没有合适的非参数检验方法，可能会不恰当地使用正态分布。更好的选择是从现代软件包中的几十种分布中选择适合数据的分布。选择一个能代表数据生成过程的分布是分析数据的关键步骤，但却被忽视了。本文将讨论几种可供选择的分布及其适用的数据类型。

Ditching the norm: Using alternative distributions for biological data analysis.

Most classical statistical tests assume data are normally distributed. If this assumption is not met, researchers often turn to non-parametric methods. These methods have some drawbacks, and if no suitable non-parametric test exists, a normal distribution may be used inappropriately instead. A better option is to select a distribution appropriate for the data from dozens available in modern software packages. Selecting a distribution that represents the data generating process is a crucial but overlooked step in analysing data. This paper discusses several alternative distributions and the types of data that they are suitable for.

期刊介绍： The international journal of laboratory animal science and welfare, Laboratory Animals publishes peer-reviewed original papers and reviews on all aspects of the use of animals in biomedical research. The journal promotes improvements in the welfare or well-being of the animals used, it particularly focuses on research that reduces the number of animals used or which replaces animal models with in vitro alternatives.
