A computational approach to extreme values and related hitting probabilities in level-dependent quasi-birth-death processes
Antonio Di Crescenzo, Antonio Gómez-Corral, Diana Taipe
This paper analyzes the dynamics of a level-dependent quasi-birth-death process , i.e., a bi-variate Markov chain defined on the countable state…
Modelling the random spreading of fake news through a two-dimensional time-inhomogeneous birth-death process
Antonio Di Crescenzo, Paola Paraggio
We consider a two-dimensional time-inhomogeneous birth-death process to model the time-evolution of fake news in a population. The two components of the process represent, respecti…
Statistical analysis and first-passage-time applications of a lognormal diffusion process withmulti-sigmoidal logistic mean
Antonio Di Crescenzo, Paola Paraggio, Patricia Román-Román +1
We consider a lognormal diffusion process having a multisigmoidal logistic mean, useful to model the evolution of a population which reaches the maximum level of the growth after m…
Applications of the multi-sigmoidal deterministic and stochastic logistic models for plant dynamics
Antonio Di Crescenzo, Paola Paraggio, Patricia Román-Román +1
We consider a generalization of the classical logistic growth model introducing more than one inflection point. The growth, called multi-sigmoidal, is firstly analyzed from a deter…
