A fast EM algorithm for fitting marked Markovian arrival processes with a new special structure [PDF]

open access: yes, 2013
This paper presents an EM algorithm for fitting traces with Markovian arrival processes (MAPs). The proposed algorithm operates on a special subclass of MAPs.

Finite dimensional Markovian realizations for stochastic volatility forward rate models [PDF]

open access: yes
We consider forward rate rate models of HJM type, as well as more general infinite dimensional SDEs, where the volatility/diffusion term is stochastic in the sense of being driven by a separate hidden Markov process.

Stability criteria for controlled queueing networks [PDF]

open access: yes, 2006
We give criteria for the stability of a very general queueing model under different levels of control. A complete classification of stability (or positive recurrence), transience and null-recurrence is presented for the two queue model. The stability and

Spatial Synchronous Markovian Arrival Orocess (Spatial SynchMAP)

open access: yes
This paper introduces and analyzes the Spatial Synchronous Markovian Arrival Process (Spatial SynchMAP), a novel extension of classical Markovian arrival processes that simultaneously captures temporal dynamics through a finite state space {1, ...,K ...

On Filtering in Markovian Term Structure Models (An Approximation Approach) [PDF]

open access: yes
We study a nonlinear filtering problem to estimate, on the basis of noisy observations of forward rates, the market price of interest rate risk as well as the parameters in a particular term structure model within the Heath-Jarrow-Morton family.

Forward Rate Dependent Markovian Transformations of the Heath-Jarrow-Morton Term Structure Model [PDF]

open access: yes
In this paper, a class of forward rate dependent Markovian transformations of the Heth-Jarrow-Morton [HJM92] term structure model are obtained by considering volatility processes that are solutions of linear ordinary differential equations.
