Fluctuation theory for one-sided Lévy processes with a matrix-exponential time horizon

Mogens Bladt, Jevgenijs Ivanovs

There is an abundance of useful fluctuation identities for one-sided Lévy processes observed up to an independent exponentially distributed time horizon. We show that all the funda…

Multivariate phase-type theory for the site frequency spectrum

Asger Hobolth, Mogens Bladt, Lars Nørvang Andersen

Linear functions of the site frequency spectrum (SFS) play a major role for understanding and investigating genetic diversity. Estimators of the mutation rate (e.g. based on the to…

Fitting inhomogeneous phase-type distributions to data: the univariate and the multivariate case

Hansjoerg Albrecher, Mogens Bladt, Jorge Yslas

The class of inhomogeneous phase-type distributions (IPH) was recently introduced in Albrecher and Bladt (2019) as an extension of the classical phase-type (PH) distributions. Like…

Multivariate fractional phase--type distributions

Hansjoerg Albrecher, Martin Bladt, Mogens Bladt

We extend the Kulkarni class of multivariate phase--type distributions in a natural time--fractional way to construct a new class of multivariate distributions with heavy-tailed Mi…

Multivariate Matrix Mittag--Leffler distributions

Hansjoerg Albrecher, Martin Bladt, Mogens Bladt

We extend the construction principle of multivariate phase-type distributions to establish an analytically tractable class of heavy-tailed multivariate random variables whose margi…

Matrix Mittag--Leffler distributions and modeling heavy-tailed risks

Hansjoerg Albrecher, Martin Bladt, Mogens Bladt

In this paper we define the class of matrix Mittag-Leffler distributions and study some of its properties. We show that it can be interpreted as a particular case of an inhomogeneo…
