Moderating the Mediation Bootstrap for Causal Inference

Autor: van Garderen, Kees Jan, van Giersbergen, Noud

Mediation analysis is a form of causal inference that investigates indirect effects and causal mechanisms. Confidence intervals for indirect effects play a central role in conducting inference. The problem is non-standard leading to coverage rates th

Optimizing importance weighting in the presence of sub-population shifts

Autor: Holstege, Floris, Wouters, Bram, van Giersbergen, Noud, Diks, Cees

A distribution shift between the training and test data can severely harm performance of machine learning models. Importance weighting addresses this issue by assigning different weights to data points during training. We argue that existing heuristi

Improved Tests for Mediation

Autor: Hillier, Grant, van Garderen, Kees Jan, van Giersbergen, Noud

Testing for a mediation effect is important in many disciplines, but is made difficult - even asymptotically - by the influence of nuisance parameters. Classical tests such as likelihood ratio (LR) and Wald (Sobel) tests have very poor power properti

Removing Spurious Concepts from Neural Network Representations via Joint Subspace Estimation

Autor: Holstege, Floris, Wouters, Bram, van Giersbergen, Noud, Diks, Cees

Out-of-distribution generalization in neural networks is often hampered by spurious correlations. A common strategy is to mitigate this by removing spurious concepts from the neural network representation of the data. Existing concept-removal methods

Shallow drainage of agricultural peatlands without land-use change: have your peat and eat it too

Autor: T. S. Heuts, Q. van Giersbergen, R. Nouta, T. P. A. Nijman, R. C. H. Aben, O. van der Scheer, P. G. M. Heuts, L. J. Skovsholt, G. R. Quadra, A. J. P. Smolders, C. Fritz

IntroductionDrainage for agricultural purposes is one of the main drivers of peatland degradation, leading to significant greenhouse gas (GHG) emissions, biodiversity loss, and soil eutrophication. Rewetting is a potential solution to restore peatlan
