Correlation function analysis<br />
Time series data, f(t), and many relaxation<br />
phenomena, are often easy to characterize<br />
by correlation functions:<br />
The angular brackets denote averaging over<br />
all possible time-origins,t, in the trajectory;<br />
for a stationary process t is often omitted<br />
(replaced by ”0”); τ is the lag-time.<br />
