径向图是一种图形显示，用于比较具有不同精度的估计。它是标准化估计相对于标准误差的倒数的散点图，可能是相对于转换后的尺度，其设计目的是使原始估计可以进行比较和解释。估计可能是均值、回归系数、比例、比率、优势比、随机效应，或者实际上是任何值得在个体或群体之间进行比较的参数估计。本文通过讨论取自文献的各种数据实例来说明径向图的一些用途。统计应用领域包括实验室间试验、点过程事件率、经验贝叶斯估计、计数数据建模、过分散和欠分散二项和泊松数据分析、混合建模和元分析。
A radial plot is a graphical display for comparing estimates that have differing precisions. It is a scatter plot of standardized estimates against reciprocals of standard errors, possibly with respect to a transformed scale, designed so that the original estimates can be compared and interpreted. The estimates may be means, regression coefficients, proportions, rates, odds ratios, random effects, or indeed any parameter estimates that merit comparison between individuals or groups. This article illustrates some uses of radial plots by discussing a variety of data examples taken from the literature. The statistical application areas include interlaboratory trials, point process event rates, empirical Bayes estimation, modeling of counting data, analysis of overdispersed and underdispersed binomial and Poisson data, mixture modeling and meta-analysis.
