Analytical and easily calculated expressions for continuous commutation functions under Gompertz-Makeham mortality
Andreas Nordvall Lagerås
It is known, but perhaps not well-known, that when the mortality is assumed to be of Gompertz-Makeham-type, the expected remaining life-length and the commutation functions used fo…
Copulas for Markovian dependence
Andreas N. Lagerås
Copulas have been popular to model dependence for multivariate distributions, but have not been used much in modelling temporal dependence of univariate time series. This paper dem…
Supercritical general branching processes conditioned on extinction are subcritical
Peter Jagers, Andreas Nordvall Lagerås
It is well known that a simple, supercritical Bienaymé-Galton-Watson process turns into a subcritical such process, if conditioned to die out. We prove that the corresponding holds…
Reduced branching processes with very heavy tails
Andreas N. Lagerås, Serik Sagitov
The reduced Markov branching process is a stochastic model for the genealogy of an unstructured biological population. Its limit behavior in the critical case is well studied for t…
A population model for -coalescents with neutral mutations
Andreas Nordvall Lagerås
Bertoin and Le Gall (2003) introduced a certain probability measure valued Markov process that describes the evolution of a population, such that a sample from this population woul…
