Revisiting Simpson's Paradox: a statistical misspecification perspective

, 2016
The primary objective of this paper is to revisit Simpson's paradox using a statistical misspecification perspective. It is argued that the reversal of statistical associations is sometimes spurious, stemming from invalid probabilistic assumptions ...

Robust Design and Misspecification Detection for Count Models

Count models, such as the Poisson and negative binomial models, are widely utilized in various fields, including epidemiology, engineering, and social sciences, to model the occurrence of events within fixed periods of time or space.

The Psychometric Properties and Clinical Usefulness of the Difficulties in Emotion Regulation Scale in Forensic Settings

Journal of Clinical Psychology, EarlyView.
ABSTRACT Objective The Difficulties in Emotion Regulation Scale (DERS) is a widely used measure of emotion dysregulation across clinical contexts. However, its psychometric properties and clinical utility have not been thoroughly examined in forensic populations.

Corticosterone and Mitochondrial Efficiency Are Associated With Changes in DNA Oxidative Damage During an Acute Stress Response in Leach's Storm‐Petrels (Hydrobates leucorhous)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The ability of organisms to effectively respond to challenges is critical for survival. We investigated how an acute stressor affected corticosterone, mitochondrial function, and DNA oxidative damage in a wild population of Leach's storm‐petrels (Hydrobates leucorhous).

Exchange Rate Expectations and Functional Misspecification.

The authors employ the Cooley-Prescott adaptive model to examine for functional misspecification in three commonly used exchange rate expectation models. They also test for heterogeneity among forecasts.

Guidelines for Meta‐Analytic Structural Equation Modeling: Steps, Resources, and Illustrations

Psychology &Marketing, EarlyView.
ABSTRACT The goal of science is to build incremental, structured, and reliable knowledge over time. Yet, many strands of marketing and related disciplines exhibit symptoms of cumulative stagnation, including lack of replicability and weak theoretical integration. Existing remedies such as replication studies, multistudy investigations, and open science

Optimal Experimental Design for Fast and Accurate Relaxation Time Measurements in Magnetic Resonance

Magnetic Resonance in Chemistry, EarlyView.
We apply D‐optimal experimental design to relaxation constant estimation in NMR relaxometry. The resulting sampling schedules concentrate measurements where the signal is most sensitive to the relaxation constant. Compared with conventional linear or logarithmic spacing, D‐optimal designs achieve better estimation accuracy and precision with fewer ...
