Third Workshop on Higher-Order Asymptotics and Post-Selection Inference

第三届高阶渐近与后选择推理研讨会（WHOA-PSI）将于2018年9月8日至10日在华盛顿大学圣路易斯校区举行。后选择推理是指在使用模型选择程序后进行有效统计推理的问题。高阶渐近提供了必要的工具和见解，以完善基本的大样本结果，用于后选择推理程序，并使其更加准确和强大，即使科学家只能访问小到中等样本量。WHOA-PSI寻求合并这些领域，促进合作和讨论，并推动后选择推理研究前沿向更高阶精度和更强大的推理程序的方向发展。美国国家科学基金会将资助参加本次会议的初级研究人员。本次研讨会试图解决应用统计学家利用模型选择程序的需求，他们也需要具有理论保证的极其准确和强大的推理程序。后选择推理的主题包括变量选择后的选择性推理、高维和后正则化推理、变点估计后的推理和同时推理。一些讲座将集中在高阶渐近方法上，这些方法可以对后选择推理过程产生见解和改进，包括级数展开、鞍点近似和基于自举的改进。另外的会谈将介绍需要新的后选择方法的重要应用问题。例子包括统计遗传学、神经科学和金融学。（见http://www.math.wustl.edu/~kuffner/WHOA-PSI-3.html）This该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，认为值得支持。

The Third Workshop on Higher-Order Asymptotics and Post-Selection Inference (WHOA-PSI) will be held on the campus of Washington University in St. Louis from September 8-10, 2018. Post-selection inference refers to the question of valid statistical inference performed after a model selection procedure has been utilized. Higher-order asymptotics provide the tools and insights needed to refine basic large-sample results for post-selection inference procedures and make them more accurate and powerful, even when the scientist only has access to small to moderate sample sizes. WHOA-PSI seeks to merge these fields, foster collaboration and discussion, and push forward the post-selection inference research frontier in the direction of higher-order accuracy and more powerful inference procedures. NSF funding will support junior researchers attending this conference.This workshop attempts to address the needs of applied statisticians utilizing model selection procedures who also need extremely accurate and powerful inference procedures with theoretical guarantees. Topics from post-selection inference include selective inference after variable selection, high-dimensional and post-regularized inference, inference after change-point estimation, and simultaneous inference. Some talks will focus on methods from higher-order asymptotics, which can yield insights and improvements to post-selection inference procedures, including series expansions, saddlepoint approximations, and bootstrap-based refinements. Additional talks will present important applied problems for which new post-selection methods are needed. Examples include statistical genetics, neuroscience, and finance.
