Abstract

We use an empirical study based on simple Monte Carlo integrations to exhibit the well known long-range correlations between linear congruential random numbers. In contrast to former studies, our long-range correlation test is carried out to assess more than only two parallel streams. In addition we perform our test also with explicit inversive generators which from the theoretical point of view have to be stable against long-range correlations.
