论文摘要
我们研究了不匹配的似然比测试的问题。我们分析了类型 - \ rnum {1}和\ rnum {2}错误指数时,当生成观察值的实际分布与测试中使用的分布不同时。当生成数据的实际分布在测试分布的相对熵球内时,我们得出了最坏情况误差指数。此外,我们研究了测试对小相对熵球的敏感性。
We study the problem of mismatched likelihood ratio test. We analyze the type-\RNum{1} and \RNum{2} error exponents when the actual distributions generating the observation are different from the distributions used in the test. We derive the worst-case error exponents when the actual distributions generating the data are within a relative entropy ball of the test distributions. In addition, we study the sensitivity of the test for small relative entropy balls.
