Broadly Applicable Approximate MCMC for Switching Stochastic Differential Equations Using Uniformization and Time-Conditioned Factorized Neural Likelihood Estimation

This paper proposes a broadly applicable approximate Markov chain Monte Carlo sampler for switching stochastic differential equations that combines uniformization with time-conditioned factorized neural likelihood estimation to overcome the limitations of existing methods by enabling Bayesian inference without requiring analytically tractable transition densities.

Before Nonresponse: School-Relative Response Timing and Selective Observability in PISA 2025 Context Questionnaires in Latin America

This study of PISA 2025 data from Latin America reveals that late questionnaire nonresponse is often preceded by sustained rapid responding, a transition linked to school-level socioeconomic factors and peer timing, which leads to selective observability that slightly biases regional study-planning estimates but highlights the value of response timing data for distinguishing response quality from missingness.

How Much of the Engagement–Performance Association Survives Adjustment? A Double Machine Learning Study in Online Higher Education

Using double machine learning on a large-scale dataset, this study reveals that while pre-submission online engagement does predict academic performance, nearly half of the raw association is attributable to confounding factors like prior attainment, highlighting the critical need to distinguish predictive signals from causal effects in learning analytics.

Impact of Lifestyles and Social Attitudes on Happiness Based on CGSS Phase II Modular Data

This study utilizes Bayesian BRPN and FBRPN variable screening within survey-year-adjusted logistic regression models on CGSS Phase II data to identify a comprehensive hierarchy of lifestyle, social attitude, and socio-demographic factors that significantly influence happiness, while also contextualizing the methodological choice through a discussion of the Bayesian–Frequentist debate.

National assignment rate and time to assignment of the Spanish NIE (Número de Identidad de Extranjero) in 2026: a retrospective analysis of 159 certificates with projections for 2027

This retrospective analysis of 159 NIE certificates issued between April and September 2026 estimates a national assignment rate of approximately 940,000 for the year and a median processing time of 10 days, while noting significant limitations regarding data representativeness, funding conflicts, and the absence of ethics approval.
