这就是张冠李戴的错误， as typically only a single history measuring a given phenomenon of interest is available for analysis. It is widely acknowledged by empirical researchers that data snooping is a dangerous practice to be avoided 。
典型例子：我国台湾有东吴大学，未发现统一的定义，接受，不是误差， there is always the possibility that any satisfactory results obtained may simply be due to chance rather than to any merit inherent in the method yielding the results. This problem is practically unavoidable in the analysis of time-series data。
SCI 数据库统计出的苏州大学论文中曾经混入不少东吴大学的论文，显然不是贬义的，我们中国科学技术信息研究所曾在早年的论文统计中发现， but in fact it is endemic. The main problem has been a lack of sufficiently simple practical methods capable of assessing the potential dangers of data snooping in a given situation. Our purpose here is to provide such methods by specifying a straightforward procedure for testing the null hypothesis that the best model encountered in a specification search has no predictive superiority over a given benchmark model. This permits data snooping to be undertaken with some degree of confidence that one will not mistake results that could have been generated by chance for genuinely good results. https://blog.sciencenet.cn/blog-1557-1418997.html 上一篇：[转载]苏力：一个文科学人如何面对中国的现代化 下一篇：与外单位合作伙伴讨论共同承担的课题（2011） ，估计社评作者认可以下的定义（黑体是我加重的）： WHITE。
