نویسندگان

چکیده

Nous obtenons des inégalités de concentration uniformes pour analogues en temps continu processus empiriques ainsi que intégrales stochastiques diffusions scalaires ergodiques associées. De ce fait, nous posons les bases requises l’étude propriétés norme-sup procédures d’estimation d’une vaste classe diffusion. Dans le contexte i.i.d. classique, un outil-clé l’analyse statistique est celui type Talagrand. Comme substitut à ces outils dans cadre diffusions, présentons une approche systématique et auto-contenue telles l’aide d’approximation par martingales bornes moments obtenues la méthode du chaînage générique. Les probabilistes développés sont d’intérêt indépendant peuvent servir point départ d’autres tels Markov plus généraux, particulier multivariées ou observées discrets. première application concrète, analysons l’erreur l’estimation densité invariante diffusion ergodique, respectivement l’estimateur local classique non-paramétrique noyau densité.

Asymptotic Statistical Equivalence for Scalar Ergodic Diffusions

For scalar diffusion models with unknown drift function asymptotic equivalence in the sense of Le Cam’s deficiency between statistical experiments is considered under long-time asymptotics. A local asymptotic equivalence result is established with an accompanying sequence of simple Gaussian shift experiments. Corresponding globally asymptotically equivalent experiments are obtained as compound ...

Ergodic Control of Switching Diffusions*

A bstract . We study the ergodic control problem of switching diffusions representing a typical hybrid system that arises in numerous applications such as fault-tolerant control systems, flexible manufacturing systems, etc. Under fairly general conditions, we establish the existence of a stable, nonrandomized Markov policy which almost surely minimizes the pathwise long-run average cost. We the...

Ergodic Control of Reflected Diffusions with Jumps

We discuss ergodicity properties of a controlled jumps diffusion process reflected from the boundary of a bounded domain. The control parameters act on the drift term and on a first order type jump density. The controlled process is generated via a Girsanov change of probability, and a long run average criterion is to be optimized. By means of the Hamilton-Jacobi-Bellman equation, an optimal st...

Singular Perturbations in Ergodic Control of Diffusions

Ergodic control of a non-degenerate diffusion with two timescales is studied in the limiting case as the time-scale separation increases to infinity. It is shown that the limit problem is another ergodic control problem for the slow time-scale component alone with its dynamics averaged over the (controlled) invariant probability measures for the fast component. These measures in turn can be tre...
