Scale Invariance in Stochastic Processes
If is the average, expected power at frequency, then noise scales as
with for white noise, for pink noise, and for Brownian noise (and more generally, Brownian motion).
More precisely, scaling in stochastic systems concerns itself with the likelihood of choosing a particular configuration out of the set of all possible random configurations. This likelihood is given by the probability distribution. Examples of scale-invariant distributions are the Pareto distribution and the Zipfian distribution.

Famous quotes containing the words scale and/or processes:
“I have spent all my life under a Communist regime, and I will tell you that a society without any objective legal scale is a terrible one indeed. But a society with no other scale but the legal one is not quite worthy of man either.”
—Alexander Solzhenitsyn (b. 1918)
“Our bodies are shaped to bear children, and our lives are a working out of the processes of creation. All our ambitions and intelligence are beside that great elemental point.”
—Phyllis McGinley (1905–1978)
