STICERD Econometrics Seminar Series
Asymptotic Representations for Sequential Decisions, Adaptive Experiments, and Batched Bandits
Jack Porter (University of Wisconsin–Madison), joint with Keisuke Hirano
Thursday 09 May 2024 14:00 - 15:30
Many of our seminars and public events this year will continue as in person or as hybrid (online and in person) events. Please check our website listings and Twitter feed @STICERD_LSE for updates.
Unless otherwise specified, in-person seminars are open to the public. Please ensure you have informed the event contact as early as possible.
Those unable to join the seminars in-person are welcome to participate via zoom if the event is hybrid.
About this event
We develop asymptotic approximation results that can be applied to sequential estimation and infer- ence problems, adaptive randomized controlled trials, and other statistical decision problems that involve multiple decision nodes with structured and possibly endogenous information sets. Our results extend the classic asymptotic representation theorem used extensively in efficiency bound theory and local power analysis. In adaptive settings where the decision at one stage can affect the observation of variables in later stages, we show that a limiting data environment characterizes all limit distributions attainable through a joint choice of an adaptive design rule and statistics applied to the adaptively generated data, under local alternatives. We illustrate how the theory can be applied to study the choice of adaptive rules and end-of-sample statistical inference in batched (groupwise) sequential adaptive experiments.
STICERD Econometrics seminars are held on Thursdays in term time at 14.00-15.30, in SAL 3.05, unless specified otherwise.
Seminar organisers: Dr Yike Wang, Professor Tai Otsu, and Dr Vassilis Hajivassiliou.
