Observations on robust diffusive stability and common Lyapunov functions
Blake McGrane-Corrigan, Rafael de Andrade Moral, Oliver Mason
We consider the problem of robust diffusive stability (RDS) for a pair of coupled stable discrete-time positive linear-time invariant (LTI) systems. We first show that the existenc…
Non-Heuristic Selection via Hybrid Regularized and Machine Learning Models for Insurance
Luciano Ribeiro Galvão, Rafael de Andrade Moral
In this study, machine learning models were tested to predict whether or not a customer of an insurance company would purchase a travel insurance product. For this purpose, seconda…
Diagnosing overdispersion in longitudinal analyses with grouped nominal polytomous data
Maria Letícia Salvador, Gabriel Rodrigues Palma, Rafael de Andrade Moral +1
Experiments in Agricultural Sciences often involve the analysis of longitudinal nominal polytomous variables, both in individual and grouped structures. Marginal and mixed-effects…
A goodness-of-fit diagnostic for count data derived from half-normal plots with a simulated envelope
Darshana Jayakumari, Jochen Einbeck, John Hinde +2
Traditional methods of model diagnostics may include a plethora of graphical techniques based on residual analysis, as well as formal tests (e.g. Shapiro-Wilk test for normality an…
A density-dependent metapopulation model: Extinction, persistence and source-sink dynamics
Blake McGrane-Corrigan, Oliver Mason, Rafael de Andrade Moral
We consider a nonlinear coupled discrete-time model of population dynamics. This model describes the movement of populations within a heterogeneous landscape, where the growth of s…
