Maximum-Likelihood Estimation For Diffusion Processes Via Closed-Form Density Expansions
asymptotic expansion diffusion discrete observation maximum-likelihood estimation transition density
2016/1/25
This paper proposes a widely applicable method of approximate maximum-likelihood estimation for multivariate diffusion process from discretely sampled data. A closed-form asymptotic expansion for tran...
Approximation of epidemic models by diffusion processes and their statistical inference
Approximation epidemic models diffusion processes their statistical inference
2013/6/14
Among various mathematical frameworks, multidimensional continuous-time Markov jump processes $(Z_t)$ on $\N^d$ form a natural set-up for modeling $SIR$-like epidemics. In this study we extend the res...

Adaptive LASSO-type estimation for ergodic diffusion processes
discretely observed diffusion processes model selection oracle proper-ties random fields stochastic differential equations
2010/3/10
The LASSO is a widely used statistical methodology for simultaneous estimation
and variable selection. In the last years, many authors analyzed this technique from
a theoretical and applied point of...

Excursions Into a New Duality Relation for Diffusion Processes
Excursions Diffusion Processes
2009/5/12
This work was motivated by the recent work by H. Dette, J. Pitman and W.J. Studden on a new duality relation for random walks. In this note we consider the diffusion process limit of their result, and...
On the Goodness-of-Fit Testing for Ergodic Diffusion Processes
Cramer-von Mises type tests diffusion process goodness of fit hypotheses testing ergodic diffusion
2010/3/19
We consider the goodness of fit testing problem for ergodic diffusion
processes. The basic hypothesis is supposed to be simple. The
diffusion coefficient is known and the alternatives are described ...

2010/3/19
The two parameter Poisson-Dirichlet distribution PD( , ) is the distribution
of an infinite dimensional random discrete probability. It is
a generalization of Kingman’s Poisson-Dirichlet distributi...

A test for model specification of diffusion processes

2010/4/26
We propose a test for model specification of a parametric diffusion
process based on a kernel estimation of the transitional density of
the process. The empirical likelihood is used to formulate a s...
