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.

Comparación entre árboles de regresión CART y regresión Lineal [PDF]
, 2013 Resumen: La Regresión lineal es el método más usado en estadística para predecir valores de variables continuas debido a su fácil interpretación, pero en muchas situaciones los supuestos para aplicar el modelo no se cumplen y algunos usuarios tienden a ...

Canadian Journal of Statistics, EarlyView.Abstract This article presents a strategy for conducting regression analysis of zero‐truncated recurrent event data. The research is partly motivated by a pediatric mental health care (PMHC) program based on administrative data. We are particularly interested in how the occurrence of an event depends on its past occurrences and the associated ...

Polynomial Poisson algebras: Gel'fand-Kirillov problem and Poisson spectra [PDF]
, 2014 We study the fields of fractions and the Poisson spectra of polynomial Poisson algebras. First we investigate a Poisson birational equivalence problem for polynomial Poisson algebras over a field of arbitrary characteristic.

Intensity estimation of non-homogeneous Poisson processes from shifted trajectories [PDF]
, 2013 In this paper, we consider the problem of estimating nonparametrically a mean pattern intensity λ from the observation of n independent and non-homogeneous Poisson processes N1,…,Nn on the interval [0,1].

Sparse maximum likelihood estimation of regression models
Canadian Journal of Statistics, EarlyView.Abstract For regression model selection and estimation, we study a small set of candidate models of maximum likelihood from which all information criteria such as the Akaike information criterion (AIC) and the Bayesian information criterion (BIC) choose their models.

Wildlife Monographs, Volume 226, Issue 1, September 2026.We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low

Comparación de la Regresión GINI con la Regresión de Mínimos Cuadrados Ordinarios y otros modelos de regresión lineal robustos [PDF]
, 2015 El método de los Mínimos Cuadrados Ordinarios - OLS - es uno de los más usados para estimar la relación entre una variable dependiente (Y) e independientes (X). El modelo de regresión está dado por la relación Y=Xβ+ε.

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.
