[2608.19903] Where Does the Union Bound Go? Best-Arm Identification and Strong FWER Control

|
By de Heide
| arXiv
In fixed-confidence best-arm identification, proofs often use a union bound across the competing arms. From a multiple-testing point of view this can look puzzling: if the best arm is unique, only one hypothesis of the form ``arm $i$ is best'' can be true. Why then should there be a Bonferroni-type factor of $K-1$?

[1906.07801] Safe Testing

|
By de Heide
| arXiv
Authors:Peter Grünwald, Rianne de Heide, Wouter Koolen (Submitted on 18 Jun 2019) Abstract: We present a new theory of hypothesis testing. The main concept is the S-value, a notion of evidence which, unlike p-values, allows for effortlessly combining evidence from several tests, even in the common scenario where the decision to perform a new test depends on the previous test outcome: safe tests based on S-values generally preserve Type-I error guarantees under such "optional continuation".
