Farmers' preferences for eco-friendly nets as an alternative to insecticides in Africa [PDF]
Vegetable production in Africa is highly dependent on pesticides with a large proportion of the population involved in farming. We investigate if eco-friendly nets (EFNs) are a viable and accepted alternative to farmer's current practice of extreme use ...

Excursion theory for Markov processes indexed by Lévy trees
Abstract We develop an excursion theory that describes the evolution of a Markov process indexed by a Lévy tree away from a regular and instantaneous point x$x$ of the state space. The theory builds upon a notion of local time at x$x$ that was recently introduced in the companion paper [Probab. Theory Related Fields. 189 (2024), 1–99].

Tree-based conditional copula estimation
This article proposes a regression tree procedure to estimate conditional copulas. The associated algorithm determines classes of observations based on covariate values and fits a simple parametric copula model on each class.
