Improving online FDR procedures via online analogs of e-closure and compound e-values

Ziyu Xu, Lasse Fischer, Aaditya Ramdas

In many scientific applications, hypotheses are generated and tested continuously in a stream. We develop a framework for improving online multiple testing procedures with false di…

Bringing Closure to False Discovery Rate Control: A General Principle for Multiple Testing

Ziyu Xu, Aldo Solari, Lasse Fischer +3

We present a novel necessary and sufficient principle for multiple testing methods controlling an expected loss. This principle asserts that every such multiple testing method is a…

Improving Wald's (approximate) sequential probability ratio test by avoiding overshoot

Lasse Fischer, Aaditya Ramdas

Wald's sequential probability ratio test (SPRT) is a cornerstone of sequential analysis. Based on desired type-I, II error levels , it stops when the likelihood ratio crosses…

An online generalization of the (e-)Benjamini-Hochberg procedure

Lasse Fischer, Ziyu Xu, Aaditya Ramdas

In online multiple testing, the hypotheses arrive one by one, and at each time we must immediately reject or accept the current hypothesis solely based on the data and hypotheses o…

Admissible online closed testing must employ e-values

Lasse Fischer, Aaditya Ramdas

In contemporary research, data scientists often test an infinite sequence of hypotheses one by one, and are required to make real-time decisions without knowing th…
