The weighted spectral test: diaphony

Published: 01 January 1998 Publication History

Abstract

In this article, we present a new approach to assessing uniform random number generators, the weighted spectral test, or diaphony. In contrast to the usual spectral test the weighted spectral test is not limited to random number generators with a lattice structure. Its computational complexity is O (s·N2) for any point set of cardinality N in the s-dimensional unit cube. As the main results of this article, we prove an analog of the classical inequality of Erdös-Turán-Koksma, present the necessary tools to transcribe known discrepancy bounds into bounds for diaphony, and provide bounds for the diaphony of multiplicative congruetial pseudorandom numbers. The last section contains numerical results.
