More power by using fewer permutations by Koning, Nick W

“…It is conventionally believed that permutation-based testing methods should ideally use all permutations. We challenge this by showing that we can sometimes…”

Continuous Testing by Koning, Nick W

“…Testing has developed into the fundamental statistical framework for falsifying hypotheses. Unfortunately, tests are binary in nature: a test either rejects a…”

Post-hoc $\alpha$ Hypothesis Testing and the Post-hoc $p$-value by Koning, Nick W

“…An unfortunate feature of traditional hypothesis testing is the necessity to pre-specify a significance level $\alpha$ to bound the size of the test: its…”

Post-hoc and Anytime Valid Permutation and Group Invariance Testing by Koning, Nick W

“…We study post-hoc ($e$-value-based) and post-hoc anytime valid inference for testing exchangeability and general group invariance. Our methods satisfy a…”

More Power by using Fewer Permutations by Koning, Nick W

“…It is conventionally believed that a permutation test should ideally use all permutations. If this is computationally unaffordable, it is believed one should…”

Choosing alpha post hoc: the danger of multiple standard significance thresholds by Hemerik, Jesse, Koning, Nick W

“…A fundamental assumption of classical hypothesis testing is that the significance threshold $\alpha$ is chosen independently from the data. The validity of…”

More Efficient Exact Group-Invariance Testing: using a Representative Subgroup by Koning, Nick W, Hemerik, Jesse

“…Non-parametric tests based on permutation, rotation or sign-flipping are examples of group-invariance tests. These tests test invariance of the null…”

Assessing solution quality in risk-averse stochastic programs by van Beesten, E. Ruben, Koning, Nick W, Morton, David P

“…In an optimization problem, the quality of a candidate solution can be characterized by the optimality gap. For most stochastic optimization problems, this gap…”
