USING CONFIDENCE INTERVALS IN SUPPLY CHAIN AND OPERATIONS RESEARCH*
指出供应链管理研究过度依赖假设检验方法，而该方法常被误用，因此推荐使用置信区间作为更优的统计推断方法，并通过实例展示其优势，最后提出改进研究质量的建议。
Like research throughout the entire business discipline, supply chain management research has relied almost exclusively on hypothesis testing methods. This is unfortunate as hypothesis tests are routinely misinterpreted in scientific research. We explain the limitations of hypothesis testing and recommend the use of confidence intervals as the preferred inferential statistical method. In particular, the additional information provided by confidence interval methods is highlighted using several supply chain management examples. We conclude with a set of recommendations designed to enhance the quality of supply chain management research.
