The SRV data for a typical walker shown in Figure
2.24
used to construct the logarithm of the
aggregated variance and the logarithm of the aggregated mean (indicated by the dots), starting
with all the data points at the lower left, to the aggregation of twenty data points at the upper
right. The SRV data curve lies between the extremes of uncorrelated random noise (lower
dashed curve), and regular deterministic process (upper dashed curve) with a fractal dimension
of
