Abstract
We study the fluctuations in the correlation exponent obtained for correlated and noncorrelated sequences by mapping them into a one-dimensional random-walk model. We investigate, both numerically and analytically, the widely used technique of averaging over overlapping samples. An explicit quantitative measure for the reduction of the sample-to-sample fluctuations in the exponent due to this process is given, and the limits for which the results obtained are reliable are discussed.
