Preferent Compression Bounds Are Tight
Dario Paccagnan, Marius Tirlea
The lack of rigorous safety and performance certificates remains a key bottleneck to the deployment of modern learning-based methods. Sample compression has recently emerged as a p…
Permutation Testing for Monotone Trend
Joseph P. Romano, Marius A. Tirlea
In this paper, we consider the fundamental problem of testing for monotone trend in a time series. While the term "trend" is commonly used and has an intuitive meaning, it is first…
Least Squares-Based Permutation Tests in Time Series
Joseph P. Romano, Marius A. Tirlea
This paper studies permutation tests for regression parameters in a time series setting, where the time series is assumed stationary but may exhibit an arbitrary (but weak) depende…
Permutation Testing for Dependence in Time Series
Joseph P. Romano, Marius A. Tirlea
Given observations from a stationary time series, permutation tests allow one to construct exactly level tests under the null hypothesis of an i.i.d. (or, more generally, excha…
