Gaussian approximations for fast Bayesian inference of partially observed branching processes with applications to epidemiology
Angus Lewis, Antonio Parrella, John Maclean +1
We consider the problem of inference for the states and parameters of a continuous-time multitype branching process from partially observed time series data. Exact inference for th…

Weak convergence of quasi-birth-and-death processes with rational arrival process components to fluid queues
Nigel Bean, Angus Lewis
In this paper we construct a new approximation to a fluid queue as a quasi-birth-and-death process with rational arrival process components (QBD-RAP) and prove its convergence. Flu…
