Genetic model misspecification in genetic association studies
BMC Research Notes, 2017 Objective The underlying model of the genetic determinant of a trait is generally not known with certainty a priori. Hence, in genetic association studies, a dominant model might be erroneously modelled as additive, an error investigated previously.

Bayesian Inference Under Model Misspecification
The likelihood input to a Bayesian analysis almost never exactly represents how the data were generated, calling into question the validity of posterior inferences.

Business Strategy and the Environment, EarlyView.ABSTRACT ESG ratings, and in particular environmental scores (E‐scores), are becoming increasingly relevant for financial stability and capital allocation decisions. This paper investigates the relationship between corporate environmental performance and market risk, as measured through value at risk (VaR) and expected shortfall (ES), the key metrics ...

BMC Medical Research MethodologyBackground Causal mediation analysis is widespread in applied medical research, especially in longitudinal settings. However, estimating natural mediational effects in such contexts is often difficult because of the presence of post-treatment confounding.

When Does SDG Adoption Increase ESG Risk? The Mediating Role of Risk Management
Business Strategy and the Environment, EarlyView.ABSTRACT Corporate engagement with the United Nations' Sustainable Development Goals (SDGs) has expanded rapidly, yet its implications for firms' environmental, social and governance (ESG) risk remain insufficiently understood. Prior research has focused on the performance outcomes of SDG adoption while largely overlooking its potential to generate ESG

MathematicsPoisson mixed-effects models are essential for analyzing repeated count data, relying on latent random effects to account for unobserved heterogeneity and longitudinal dependence.

The relationship between excess returns, firm size and earnings on the Johannesburg Stock Exchange
South African Journal of Business Management, 1991 While considerable empirical work has been conducted in the United States concerning excess returns and the relationship of these returns to firm size and E/P ratio, thus far, there have been few similar empirical studies conducted using Johannesburg ...

Acknowledgement Misspecification in Macroeconomic Theory [PDF]
We explore methods for confronting model misspecification in macroeconomics. We construct dynamic equilibria in which private agents and policy makers recognize that models are approximations.

Business Strategy and the Environment, EarlyView.ABSTRACT Amid growing environmental pressures and sustainability challenges, understanding how institutional reforms enhance firms' ability to cope with green‐related disruptions is of substantial importance. Exploiting China's Supply Chain Innovation and Application Pilot Cities as a quasi‐natural experiment, this study investigates the impact of ...

Efficient Imitation under Misspecification
CoRRWe consider the problem of imitation learning under misspecification: settings where the learner is fundamentally unable to replicate expert behavior everywhere. This is often true in practice due to differences in observation space and action space expressiveness (e.g. perceptual or morphological differences between robots and humans).
