On the consistency of the maximum likelyhood estimate of normal mixture parameters for a sample with field structure [PDF]
General theorems concerning the strong consistency of the MLE of exponential mixture parameters are proved. These theorems imply the strong consistency of the MLE of normal mixture parameters when the data is organized into fields each of which is a ...

Food without fire: Environmental and nutritional impacts from a solar stove field experiment
American Journal of Agricultural Economics, EarlyView.Abstract Over 80% of the population in rural Sub‐Saharan Africa relies on biomass cooking fuel, a substantial source of anthropogenic greenhouse gases. We use a field experiment in Zambia to investigate the impact of solar stoves on biomass fuel use and cooking habits.

Efficient Estimation of Copula-based Semiparametric Markov Models [PDF]
This paper considers efficient estimation of copula-based semiparametric strictly stationary Markov models. These models are characterized by nonparametric invariant (one-dimensional marginal) distributions and parametric bivariate copula functions ...

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

LLM‐based prior elicitation for Bayesian graphical modeling
British Journal of Mathematical and Statistical Psychology, EarlyView.ABSTRACT In the Bayesian graphical modeling framework, priors on network structure encode theoretical assumptions and uncertainty about the topology of psychological constructs under study. For instance, the Bernoulli prior specifies the probability of each pairwise interaction, the Beta–Bernoulli prior governs expected network density, and the ...

To vary or not to vary: A flexible empirical Bayes factor for testing variance components
British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract Random effects are the gold standard for capturing structural heterogeneity, such as individual differences or temporal dependence. Yet testing their presence is difficult because variance components are constrained to be non‐negative, creating a boundary problem. This paper introduces a flexible empirical Bayes factor (EBF) for testing random

Non‐Rigid 3D Shape Correspondences: From Foundations to Open Challenges and Opportunities
Computer Graphics Forum, EarlyView.Abstract Estimating correspondences between deformed shape instances is a long‐standing problem in computer graphics; numerous applications, from texture transfer to statistical modelling, rely on recovering an accurate correspondence map. Many methods have thus been proposed to tackle this challenging problem from varying perspectives, depending on ...

Pierre‐Joseph Buc'hoz: did he deserve his bad reputation?
Curtis's Botanical Magazine, EarlyView.Summary A biography and critique of Pierre‐Joseph Buc'hoz (1731–1807) – lawyer, physician, mineralogist, naturalist, compiler and publisher – is provided. Often criticised as being a mass‐plagiariser, this is commented on, based on a detailed examination of several of his publications.

Diabetic Medicine, EarlyView.Abstract Aims Access to diabetes technology in the UK is significantly influenced by socio‐economic status, ethnicity, and systemic healthcare inequities. This study investigates barriers faced by children and young people (CYP) from ethnic minority backgrounds and/or low socio‐economic areas in accessing diabetes technologies, alongside strategies for
