Properties of Bayes Factors Based on Test Statistics

Abstract.  This article examines the consistency, interpretation and application of Bayes factors constructed from standard test statistics. Primary conclusions are that Bayes factors based on multinomial and normal test statistics are consistent for suitable choices of the hyperparameters used to specify alternative hypotheses, and that such constructions can be extended to obtain consistent Bayes factors based on likelihood ratio statistics. A connection between Bayes factors based on likelihood ratio statistics and the Bayesian information criterion is exposed, as is a connection between Bayes factors based on F statistics and parametric Bayes factors based on normal-inverse gamma models. Similarly, Bayes factors based on chi-squared statistics for multinomial data are shown to provide accurate approximations to Bayes factors based on multinomial/Dirichlet models. An illustration of how the simple form of these Bayes factors can be exploited to generate easily interpretable summaries of the experimental 'weight of evidence' is provided.     

Inference for general parametric functions in box‐Cox‐type transformation models

The authors propose a simple but general method of inference for a parametric function of the Box‐Cox‐type transformation model. Their approach is built upon the classical normal theory but takes parameter estimation into account. It quickly leads to test statistics and confidence intervals for a linear combination of scaled or unsealed regression coefficients, as well as for the survivor function and marginal effects on the median or other quantité functions of an original response. The authors show through simulations that the finite‐sample performance of their method is often superior to the delta method, and that their approach is robust to mild departures from normality of error distributions. They illustrate their approach with a numerical example.

我国农业环境会计研究的必要性分析

从四个角度分析了农业环境会计研究的必要性:一是环保运动、国际组织和协定关于促进可持续的农业和农村发展的要求为农业环境会计的研究提供了精神支持和理论依据;二是农业环境面临的严峻形势和农产品参与国际竞争是农业环境会计研究的外在要求;三是传统农业会计的缺陷是农业环境会计研究的内在要求;四是提高农业企业的环境意识,促进农业生态系统的保护。     

“同源宾语”构式与“谓语＋状语”构式的语义差别

从认知语言学的构式语法出发,以信息焦点为主线,采用核心例句She died a miserable death及Shedied miserably分别作为"同源宾语"构式和"谓语 状语"构式的典型代表,能探讨这两种构式整体语义的差别。"同源宾语"构式和"谓语 状语"构式语义等同的观点值得商榷,因为两种构式虽有相同的词汇义,但其构式义却不同,因此它们的整体语义存在很大差别,绝非等同。     

相关市场界定的主要方法及其对中国反垄断法的启示

相关市场界定作为经济分析的起点在反垄断案件中具有举足轻重的作用。市场界定是反垄断案件经济分析的起点,研究相关市场界定的方法和国外司法实践中出现的问题对于中国反垄断法的立法和执法具有重大的意义。
