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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
