Universality of e-detectors for ARL control
Aaditya Ramdas
An e-detector for a pre-change class is a nonnegative process such that for all stopping times and all $P \in \mathcal P…
Non-partitioned e-detectors for nonparametric sequential change detection
Aytijhya Saha, Aaditya Ramdas
The paper proposes non‑partitioned e‑detectors for sequential change detection when both pre‑ and post‑change distributions are unknown, using aggregated e‑processes and showing as…
Monte Carlo testing: non-asymptotic guarantees without joint exchangeability
Rina Foygel Barber, Aaditya Ramdas
In hypothesis testing, Monte Carlo tests are usually justified either by exact null simulation or by joint exchangeability of the observed data and its simulated copies. This leave…
Gaffke's confidence interval for the mean of bounded data is inadmissible but asymptotically efficient
Jiahao Ming, Aaditya Ramdas, Yi Shen +2
Given observations , Gaffke (2005) defined \[ K_n(\mathbf x)=\mathbb{P}_{\mathbf D}\!\left\{\sum_{i=1}^n x_iD_i\le 1\right\}, \qquad (D_0,D_1,\ldots,D_n)…
Testing by Betting while Borrowing and Bargaining
Hongjian Wang, Wouter M. Koolen, Aaditya Ramdas
Testing by betting has been a cornerstone of the game-theoretic statistics literature. One bets against the null hypothesis, and the accumulated wealth quantifies the evidenc…
E-values and sequential power-one tests for monotonicity and unimodality
Hongjian Wang, Aaditya Ramdas
We develop e-values and e-processes testing the null hypothesis that a distribution over nonnegative integers is monotone, and that a distribution over integers is unimodal given a…
