On the area of empty axis-parallel rectangles amidst 2-dimensional lattice points
Thomas Lachmann, Jaspar Wiart
The dispersion of a point set in the unit square is defined to be the area of the largest empty axis-parallel box. In this paper we are interested in the dispersion of lattices in…
On the distribution of scrambled -nets over unanchored boxes
C. Lemieux, J. Wiart
We introduce a new quality measure to assess randomized low-discrepancy point sets of finite size . This new quality measure, which we call "pairwise sampling dependence index",…
Walsh functions, scrambled -nets, and negative covariance: applying symbolic computation to quasi-Monte Carlo integration
Jaspar Wiart, Elaine Wong
We investigate base Walsh functions for which the variance of the integral estimator based on a scrambled -net in base is less than or equal to that of the Monte-C…
On the dependence structure and quality of scrambled nets
Jaspar Wiart, Christiane Lemieux, Gracia Y. Dong
In this paper we develop a framework to study the dependence structure of scrambled -nets. It relies on values denoted by , which are related to how m…
