Uncertainty quantification for misspecified machine learned interatomic potentials

npj Computational Materials
The use of high-dimensional regression techniques from machine learning has significantly improved the quantitative accuracy of interatomic potentials. Atomic simulations can now plausibly target quantitative predictions in a variety of settings, which ...

The Structure of Informal Learning in the Workplace—An Experience Sampling Approach

Human Resource Development Quarterly, EarlyView.
ABSTRACT This paper complements retrospective approaches to researching informal learning in the workplace with experience sampling. Since (conscious) informal learning is becoming increasingly important for successfully keeping pace with rapid changes in working environments, a clear understanding of the construct and its precise measurement are ...

Misspecification tests based on quantile residuals [PDF]

The Econometrics Journal, 2012
Summary  We develop quantile residual-based misspecification tests and apply them to non-linear time series models for which conventional residuals are unsuited. We formulate a general framework and use it to obtain computationally simple tests aimed at detecting autocorrelation, conditional heteroscedasticity and non-normality in quantile residuals ...

Explaining Variability in Employee Perceptions of HR Practices in Strategic HRM Research: An Integrative Review and Future Outlook

Human Resource Management, EarlyView.
ABSTRACT Employee perceptions of human resource (HR) practices have become a central focus in strategic human resource management (HRM) research due to their impact on individual and organizational outcomes. Recent studies highlight the importance of understanding how these perceptions are formed, what they encompass, and why they vary across employees.

Comparing performance between log-binomial and robust Poisson regression models for estimating risk ratios under model misspecification

BMC Medical Research Methodology, 2018
Background Log-binomial and robust (modified) Poisson regression models are popular approaches to estimate risk ratios for binary response variables. Previous studies have shown that comparatively they produce similar point estimates and standard errors.

What Role Do Finance Ministers Play in Political Business Cycles? Evidence‐Based on a New African Dataset

International Journal of Finance &Economics, EarlyView.
ABSTRACT This study investigates how the personal characteristics of finance ministers influence political budget cycles in Africa. Using a new dataset covering 300 finance ministers across 23 countries from 1980 to 2020, we find that political budget cycles primarily take the form of increased government consumption during election years.

Climate Change Laws and European Stock Markets: An Event Analysis

International Journal of Finance &Economics, EarlyView.
ABSTRACT Under the context of the climate change we assess the impact of EU's legislative initiative on European stock markets. Specifically, we focus on its impact on energy and Environmental Social Governance (ESG) sectors for equity returns and volatility for a representative basket of EU countries (participating also in Eurozone) as well as ...

The Impact of Changes in Real Income and the Real Effective Exchange Rate on Trade in Goods and Services

International Journal of Finance &Economics, EarlyView.
ABSTRACT We use foreign trade data on both imports and exports of goods and services among a group of 15 advanced economies to determine the incomes and price elasticities of demand for exports and imports of goods, services and goods and services combined in the long run.

A partially heterogeneous weighted fusion learning method for potential heterogeneous treatment effect in multi-site survival study

BMC Medical Research Methodology
Background In multi-site studies in clinical practice, the treatment effects may exhibit potential heterogeneity across different sites. Additionally, propensity score methods used to adjust for confounding may suffer from model misspecification, which ...
