Interacting Treatments With Endogenous Takeup

open access: yesJournal of Applied Econometrics, Volume 40, Issue 4, Page 424-437, June/July 2025.
ABSTRACT We study causal inference in randomized experiments (or quasi‐experiments) following a 2×2$$ 2\times 2 $$ factorial design. There are two treatments, denoted A$$ A $$ and B$$ B $$, and units are randomly assigned to one of four categories: treatment A$$ A $$ alone, treatment B$$ B $$ alone, joint treatment, or none. Allowing for endogenous non‐

Psychoneural reduction revised: The case of suicidality in bipolar disorder

open access: yesEuropean Journal of Neuroscience, Volume 61, Issue 1, January 2025.
Multidimensional frameworks fare better than reductionist, level‐based ones at comprehensively accounting for psychiatric phenomena. To demonstrate this, suicidality in bipolar disorder is used as a case study. In bipolar disorder, suicidality is traceable to the complex interplay of biological, psychosocial, environmental and experiential factors, and

Indication for Biases in Dry Intrusions and the Marine Boundary Layer Over the Azores in ECMWF Short‐Term Forecasts and Analyses

open access: yesGeophysical Research Letters, Volume 51, Issue 15, 16 August 2024.
Abstract The model representation of dry intrusions (DIs) and the marine boundary layer (MBL) is analyzed in the European Centre for Medium‐Range Weather Forecasts (ECMWF) Integrated Forecasting System (IFS). For this purpose, a DI classification at the Azores is combined with observation, short‐term background forecast and analysis data from the IFS ...

Nonparametric estimation of the random effects distribution for the risk or rate ratio in rare events meta‐analysis with the arm‐based and contrast‐based approaches

open access: yesStatistics in Medicine, Volume 43, Issue 4, Page 706-730, 20 February 2024.
Rare events are events which occur with low frequencies. These often arise in clinical trials or cohort studies where the data are arranged in binary contingency tables. In this article, we investigate the estimation of effect heterogeneity for the risk‐ratio parameter in meta‐analysis of rare events studies through two likelihood‐based nonparametric ...
