Beyond Prediction: Data, Baselines, Explanation, and Causation in Machine Learning for Food Insecurity

open access: yesFood Safety and Health, EarlyView.
The gains from machine learning in nowcasting and forecasting food insecurity are still small and limited and cannot be observed in all countries. This review summarizes the public resources for data, corrects common misconceptions about model requirements, and establishes baseline requirements, explanations, causal inference, and equity in operational

Nonparametric Regression for Cost‐Effectiveness Analyses With Observational Data—A Tutorial

open access: yesHealth Economics, EarlyView.
ABSTRACT Healthcare decision‐making often requires selecting among multiple treatment options under budget constraints, particularly when one option is more effective but also more costly. Cost‐effectiveness analysis (CEA) provides a framework for evaluating whether the health benefits of a treatment justify its additional costs.

Model misspecification analysis for bond options and Markovian hedging strategies [PDF]

open access: yes, 2018
In this paper, we analyse the model misspecification risk of Markovian hedging strategies for discount bond options. We show how to decompose the Profit and Loss that results from model misspecification, and emphasize the importance of the position's ...

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

open access: yesHuman 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 ...

Formative and Reflective Measurement Models in Workplace Learning Research: A Critical Review and Guidelines

open access: yesHuman Resource Development Quarterly, EarlyView.
ABSTRACT Quantitative empirical research in workplace learning regularly makes use of measurement instruments that operationalize theoretical constructs. However, in domains related to workplace learning, high levels of measurement model misspecifications—up to 62% of all cases—have been identified.

Agent‐based versus correlative models of species distributions: Evaluation of predictive performance with real and simulated data

open access: yesMethods in Ecology and Evolution
Species distribution models (SDMs) have been widely used in ecology to understand how species relate to environmental variation. Most SDMs are correlative, and they lack explicit reference to the underlying processes, and therefore, the reliability of ...

Estimation of Subtype‐Specific Tumour Growth Rate Distributions and Interval Cancer Proportions in Breast Cancer Using Biology‐Inspired Natural History Models

open access: yesInternational Journal of Cancer, EarlyView.
ABSTRACT Breast cancer progression varies across molecular subtypes, influencing detection rates and prognosis. Differences in the proportion of interval cancers (PIC)—cancers detected symptomatically between scheduled screening rounds—have been observed across subtypes, likely reflecting heterogeneity in tumour growth dynamics. We applied a continuous‐

Asymmetric Long‐Run Effects of Monetary Policy on Generational Inequality

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT This paper investigates the asymmetric long‐run effects of reversing contractionary monetary policy to expansionary policy on generational inequality in the UK using non‐linear autoregressive distributed lag (NARDL). The results show that there exists a long‐term relationship between monetary policy and income, consumption, and wealth ...

The Impact of Unemployment, Inflation, and the Exchange Rate on Economic Growth in South Africa (1994–2022)

open access: yesInternational Studies of Economics, EarlyView.
ABSTRACT South Africa's macroeconomic environment continues to be shaped by persistent structural imbalances, including high unemployment, inflationary pressures, and exchange rate fluctuations, all of which have important implications for the country's long‐term economic performance.
