Estimating Causal Effects With Observational Data: Guidelines for Agricultural and Applied Economists

open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT Most research questions in agricultural and applied economics are causal in nature: they study how changes in one or more variables (such as policies, prices or weather) affect one or more other variables (e.g., income, crop yields or pollution).

Do Training Programmes Improve Awareness of Sustainable Finance?

open access: yesAccounting &Finance, EarlyView.
ABSTRACT Many initiatives worldwide aim to improve financial knowledge through training programmes at different levels of education. In this context, it is worth highlighting that sustainable finance knowledge should receive attention in line with the global challenges (climate change, social and economic inequalities, etc.) society is facing ...

Testing for Homogeneity in Mixture Models [PDF]

open access: yes, 2016
Statistical models of unobserved heterogeneity are typically formalized as mixtures of simple parametric models and interest naturally focuses on testing for homogeneity versus general mixture alternatives.

Enhancing generalizability theory with mixed‐effects models for heteroscedasticity in psychological measurement: A theoretical introduction with an application from EEG data

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Generalizability theory (G‐theory) defines a statistical framework for assessing measurement reliability by decomposing observed variance into meaningful components attributable to persons, facets, and error. Classic G‐theory assumes homoscedastic residual variances across measurement conditions, an assumption that is often violated in ...

ReMoDe – Recursive modality detection in distributions of ordinal data

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The detection of the number of modes in distributions of ordinal data is relevant for applied researchers across disciplines, from uncovering polarization to detecting incidence groups in clinical symptom scales. Yet, established modality detection methods are either purely descriptive or not developed for ordinal data.

On the power of conditional independence testing under model-X

open access: yes, 2021
For testing conditional independence (CI) of a response Y and a predictor X given covariates Z, the recently introduced model-X (MX) framework has been the subject of active methodological research, especially in the context of MX knockoffs and their ...

Using multilabel classification neural network to detect intersectional DIF with small sample sizes

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract This study introduces InterDIFNet, a multilabel classification neural network for detecting intersectional differential item functioning (DIF) in educational and psychological assessments, with a focus on small sample sizes. Unlike traditional marginal DIF methods, which often fail to capture the effects of intersecting identities and require ...

Fused kernel-spline smoothing for repeatedly measured outcomes in a generalized partially linear model with functional single index

open access: yes, 2015
We propose a generalized partially linear functional single index risk score model for repeatedly measured outcomes where the index itself is a function of time.
