3 Jun 2024: We apply ideas from post-selection inference to randomization tests for adaptive experiments.

3 Jun 2024: March 2016Abstract. This paper uses a generalized Stolarsky’s invariance principle to approximate the permutation $p$-value for two-sample linear test statistics.

3 Jun 2024: We show that the usual likelihood ratio χ2-test is valid non-asymptotically. ... Our proof relies on expressing the test statistic as the minimum eigenvalue of a Wishart variable and using a representation of its distribution using Legendre polynomials.

3 Jun 2024: In the first part, I will use the potential outcomes framework to define the conditional randomization test, distinguish it with related ideas, and discuss some recent applications.
