On subset least squares estimation and prediction in vector autoregressive models with exogenous variables

open access: yesCanadian Journal of Statistics, Volume 54, Issue 2, June 2026.
Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based

A goodness‐of‐fit test for regression models with discrete outcomes

open access: yesCanadian 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.

From passion to illegality: Understanding succulent consumers' decision to participate in the illegal online wildlife trade

open access: yesPeople and Nature, Volume 8, Issue 6, Page 1773-1784, June 2026.
Abstract The illegal wildlife trade represents a significant threat to biodiversity. Limited research has examined the illegal trade in succulents, plants characterized by their ability to store water in their leaves, stems or roots. The growing popularity of succulents has contributed to the emergence of illicit consumer practices.

Varied motivations for secondary forest reclearing among landholders make forest persistence challenging

open access: yesPeople and Nature, Volume 8, Issue 6, Page 1943-1956, June 2026.
Abstract Remote sensing studies show that ephemeral forest regeneration is widespread in the tropics, limiting the climate and biodiversity benefits from net increases in forest cover. Socioeconomic, biophysical and landscape variables can help explain the spatial distribution of reforestation reversals.

When invasions go unnoticed: Public perception of the freshwater jellyfish Craspedacusta sowerbii in Europe

open access: yesPeople and Nature, Volume 8, Issue 6, Page 1957-1973, June 2026.
Abstract Biological invasions are a major driver of biodiversity loss, yet inconspicuous or “cryptic” species often escape detection and public awareness, limiting management responses. We investigated the freshwater jellyfish Craspedacusta sowerbii, likely native to China and now present on six continents, through a 22‐month multilingual online survey
