Strong approximation for set-indexed partial sum processes via KMT constructions III

Abstract
We generalize the results of Komlós, Major and Tusnády concerning the strong approximation of partial sums of independent and identically distributed random variables with a finite r-th moment to the case when the parameter set is two-dimensional. The most striking result is that the rates of convergence are exactly the same as in the one-dimensional case.


Résumé
Nous étendons les résultats de Komlós, Major and Tusnády sur l'approximation forte des sommes partielles de variables aléatoires réelles indépendantes et équidistribuées ayant un moment d'ordre r fini aux processus de sommes partielles avec ensemble d'indices bidimensionnel. La vitesse de convergence obtenue est identique à celle du cas unidimensionnel.


Key words: Set-indexed partial-sum process / functional central limit theorem / invariance principle / strong approximation.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
