    22 Jul 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.

    22 Jul 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.

    28 Apr 2023: You should explain carefully the assumptions underlyingthe test. 1/II/21H Statistics. State and prove the Rao–Blackwell Theorem. ... Find the best test of size α, 0 < α < 1, of the hypothesisH0 : θ = θ0 against H1 : θ = θ1, where θ1 > θ0.

  7. Selective Randomization Inference for Adaptive Experiments | Qingyuan …

    https://www.statslab.cam.ac.uk/~qz280/publication/selective-randomization/
    22 Jul 2024: In a nutshell, our approach applies conditional post-selection inference to randomization tests. ... Lastly, we demonstrate our method and compare it with other randomization tests using synthetic and real-world data.
