Fractional Inhomogeneous Multi-state Models in Life Insurance
Martin Bladt
In this paper, we demonstrate through the use of matrix calculus a transparent analysis of fractional inhomogeneous Markov models for life insurance where transition matrices commu…
Efficient simulation of ruin probabilities when claims are mixtures of heavy and light tails
Hansjörg Albrecher, Martin Bladt, Eleni Vatamidou
We consider the classical Cramér-Lundberg risk model with claim sizes that are mixtures of phase-type and subexponential variables. Exploiting a specific geometric compound represe…
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…
