应理学院应用数学系邀请,青岛大学数学与统计学院副院长李新民教授将于2018525-526日访问我校并做学术报告。

题目:Fidcuial p-value and Behrens-Fisher problem

时间:525日周五下午4:10

地点:曲江9-313

报告摘要:This talk will provide a general method for constructing generalized p-value via the fiducial inference. Furthermore, the power properties of the generalized test are discussed. The Behrens-Fisher problem is the problem in statistics of hypothesis testing and interval estimation regarding the difference between the means of two independent normal populations without assuming the variances are equal. We reconsider it using the fiducial p-value. We also propose a fiducial based test foe the equality of several normal means when the variances are unknown and unequal, and theoretically examine the frequentist property of the proposed test.  The simulation results indicate that the proposed approach can provide a reasonable p-value via a few straightforward simulation steps. Finally, the proposed approach is applied to an analysis of two real data sets for illustration.
