Dormancy stabilizes non-transitive competitive dynamics
José Chacón, Adrián González-Casanova, Imanol Nuñez +3
Competitive interactions can maintain diversity, yet coexistence is often fragile in well-mixed populations, where stochastic fluctuations can lead to extinction. This is the case…
Mode-based estimation of the center of symmetry
José E. Chacón, Javier Fernández Serrano
In the mean-median-mode triad of univariate centrality measures, the mode has been overlooked for estimating the center of symmetry in continuous and unimodal settings. This paper…
Estimation of density functionals via cross-validation
José E. Chacón, Carlos Tenreiro
In density estimation, the mean integrated squared error (MISE) is commonly used as a measure of performance. In that setting, the cross-validation criterion provides an unbiased e…
Stochastic two-patch epidemic model with nonlinear recidivism
Juan G. Calvo, Mario I. Simoy, Juan P. Aparicio +2
We develop a stochastic two-patch epidemic model with nonlinear recidivism to investigate infectious disease dynamics in heterogeneous populations. Extending a deterministic framew…
Bayesian taut splines for estimating the number of modes
José E. Chacón, Javier Fernández Serrano
The number of modes in a probability density function is representative of the complexity of a model and can also be viewed as the number of subpopulations. Despite its relevance,…
