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…
Time series models with infinite-order partial copula dependence
Martin Bladt, Alexander J. McNeil
Stationary and ergodic time series can be constructed using an s-vine decomposition based on sets of bivariate copula functions. The extension of such processes to infinite copula…
Trimmed extreme value estimators for censored heavy-tailed data
Martin Bladt, Hansjoerg Albrecher, Jan Beirlant
We consider estimation of the extreme value index and extreme quantiles for heavy-tailed data that are right-censored. We study a general procedure of removing low importance obser…
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…
