Modelos de regresión de Poisson aplicados a la propagación del COVID-19 a través del tráfico aéreo [PDF]
, 2022 La COVID-19 es una infección vírica detectada en diciembre de 2019 que se convirtió rápidamente en una pandemia mundial. Desde entonces, la necesidad de crear modelos de predicción para predecir epidemias ha ido creciendo, no solo por la necesidad en si ...

Copula‐based joint modelling of emergency department visits with time‐varying dependence
Canadian Journal of Statistics, EarlyView.Abstract Jointly modelling multiple correlated count time series is essential in health services research, where outcomes like emergency visits for mental health and substance use often evolve together. Ignoring these dependencies can obscure meaningful trends and limit the effectiveness of policy evaluation.

A goodness‐of‐fit test for regression models with discrete outcomes
Canadian Journal of Statistics, Volume 54, Issue 2, June 2026.Abstract Regression models are often used to analyze discrete outcomes, but classical goodness‐of‐fit tests such as those based on the deviance or Pearson's statistic can be misleading or have little power in this context. To address this issue, we propose a new test, inspired by the work of Czado et al.

Key drivers of at‐vessel mortality in demersal sharks
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Chondrichthyans are highly vulnerable to fisheries overexploitation, and postcapture mortality poses a significant threat to most species. Global bycatch mitigation guidelines recommend adopting hierarchical decision‐making approaches tailored to species‐specific vulnerabilities and socioeconomic and regulatory contexts.

Canadian Journal of Statistics, Volume 53, Issue 4, December 2025.Abstract Modern longitudinal data from wearable devices consist of biological signals at high‐frequency time points. Distributed statistical methods have emerged as a powerful tool to overcome the computational burden of estimation and inference with large data, but methodology for distributed functional regression remains limited.
