In this work we point out that some common methods for estimating self-similarity parameters – involving packet counting for the estimate of statistical moments – are affected by distortion at the finest resolutions and quantization errors and we illustrate – using also a small sample of the Bellcore data set – a technique for removing this undesirable effect,based on factorial moments and strip integrals. Then we extend the strip-integral approach to the approximation of the square of the Haar wavelet coefficients, for the estimate of the Hurst self-affinity exponent.

Abstract
In this work we point out that some common methods for estimating self-similarity parameters – involving packet counting for the estimate of statistical moments – are affected by distortion at the finest resolutions and quantization errors and we illustrate – using also a small sample of the Bellcore data set – a technique for removing this undesirable effect,based on factorial moments and strip integrals. Then we extend the strip-integral approach to the approximation of the square of the Haar wavelet coefficients, for the estimate of the Hurst self-affinity exponent.Pubblicazioni consigliate
