在统计分析中，对数正态分布已成为代表本质为正且往往具有高度偏态的环境数据的常见选择。然而，它的使用所产生的影响往往没有得到认真考虑。本文以放射监测应用为重点，回顾了假设对数正态分布在数据分析和解释方面的意义。文中还讨论了用正态理论方法处理对数变换后的数据与原始尺度下乘性误差和假设检验的关系。
The lognormal distribution has become a common choice to represent intrinsically positive and often highly skewed environmental data in statistical analysis. However the implications of its use are often not carefully considered. With an emphasis on radiological monitoring applications, this paper reviews what assuming lognormality means in terms of data analysis and interpretation. The relationship of using normal theory methods on log transformed data to multiplicative errors and hypothesis testing in the original scale is also discussed.
