Liese, Friedrich (DDR-FSU) 87a:60051 Hellinger integrals, error probabilities, and contiguity of Gaussian processes with independent increments and Poisson processes.  ...  In the present paper the latter complex-parameter Hellinger integral is calculated for P and Q which are distribution laws of Gaussian processes with independent increments or Poisson point processes.  ... 

Bayesian Nonparametric Analysis of Multivariate Time Series: A Matrix Gamma Process Approach [article]

Alexander Meier, Claudia Kirch, Renate Meyer
2018 arXiv   pre-print
This is in line with existing approaches for the univariate case, where the normalized spectral density is modeled similar to a probability density, e.g. with a Dirichlet process mixture of Beta densities  ...  In this work, we present a related approach for multivariate time series, with matrix-valued mixture weights induced by a Hermitian positive definite Gamma process.  ...  CRM) on X = [0, π] with independent Gamma increments to a completely random Hpd matrix-valued measure with independent matrix-Gamma increments.  ...

On the Approximation of Geometric Fractional Brownian Motion [chapter]

Esko Valkeila
2009 Optimality and Risk - Modern Trends in Mathematical Finance  
With this approximation we associate the corresponding pricing model sequence, which has no-arbitrage property and which is complete.  ...  We analyze the central limit theorem of Gaigalas and Kaj from the point of view semimartingale limit theorems to have a better understanding of the arbitrage in the limit model.  ...  Assume that with respect to the measure Q they are independent Poisson processes with intensity 1 µ , and with respect to the measure P they are independent renewal counting processes, and their interarrival  ...

Some distance bounds of branching processes and their diffusion limits [article]

Niels B. Kammerer, Wolfgang Stummer
2010 arXiv   pre-print
We compute exact values respectively bounds of "distances" - in the sense of (transforms of) power divergences and relative entropy - between two discrete-time Galton-Watson branching processes with immigration  ...  Implications for asymptotic distinguishability behaviour in terms of contiguity and entire separation of the involved GWI are given, too.  ...  We are very grateful to the "Studienstiftung des deutschen Volkes" for the generous grant of the first author. Furthermore, we would also like to thank Andreas Greven for some useful remarks.  ...

Viewed as a prior on the cumulative hazard process, the prior can be identified with an independent increment process.  ...  When Z(t) is the gamma process, that is an independent increment process with Z(t) ∼ gamma(M G(t), 1), then the resulting distribution of P is Dirichlet process Dir(M, G).  ...

On Fitting Finite Dirichlet Mixture Using ECM and MML [chapter]

Nizar Bouguila, Djemel Ziou
2005 Lecture Notes in Computer Science  
We study a fluid system with single on/off source in which the active (on) and silent periods (off) follow General and Exponential distributions respectively.  ...  The system is analysed for different active periods corresponding to the service time of an M/G/1 queue and the busy period of an M/G/1 queue.  ...  In the latter case, the process has independent increments and self-similarity exists without long-range dependence.  ...
