Mean-field interacting multi-type birth-death processes with a view to applications in phylodynamics
William S. DeWitt, Steven N. Evans, Ella Hiesmayr +1
Multi-type birth-death processes underlie approaches for inferring evolutionary dynamics from phylogenetic trees across biological scales, ranging from deep-time species macroevolu…
Progress on Constructing Phylogenetic Networks for Languages
Tandy Warnow, Steven N. Evans, Luay Nakhleh
In 2006, Warnow, Evans, Ringe, and Nakhleh proposed a stochastic model (hereafter, the WERN 2006 model) of multi-state linguistic character evolution that allowed for homoplasy and…
Increasing Gambler's Ruin duration and Brownian Motion exit times
Steven Evans, Erol A. Peköz, Rhonda Righter
In Gambler's Ruin when both players start with the same amount of money, we show the playing time stochastically increases when the games are made more fair. We give two different…
Virtual Markov chains
Steven N. Evans, Adam Q. Jaffe
We introduce the space of virtual Markov chains (VMCs) as a projective limit of the spaces of all finite state space Markov chains (MCs), in the same way that the space of virtual…
Limit Theorems for Fréchet Mean Sets
Steven N. Evans, Adam Q. Jaffe
For , the Fréchet -mean of a probability measure on a metric space is an important notion of central tendency that generalizes the usual notions in the real l…
Two continua of embedded regenerative sets
Steven N. Evans, Mehdi Ouaki
Given a two-sided real-valued Lévy process , define processes and by $L_t := \sup\{h \in \mathbb{R}…
