摘要: SUMMARY Hurst's empirical law concerning geophysical time series such as annual river flows was framed in terms of an adjusted rescaled range, namely, the range cumulative sums deviations summands from a linearly time-shifted origin, expressed units estimated standard deviation full sample. Nonsimulatory theoretical results Hurst phenomenon have hitherto been confined to without rescaling. The present paper derives expectation for independent normal summands.
