correlation integral การใช้

In chaos theory, the "'correlation sum "'is the estimator of the correlation integral, which reflects the mean probability that the states at two different times are close:
As the number of points tends to infinity, and the distance between them tends to zero, the correlation integral, for small values of " & epsilon; ", will take the form:
If the number of points is sufficiently large, and evenly distributed, a log-log graph of the correlation integral versus " & epsilon; " will yield an estimate of " ? ".
Given a signal f ( t ), the continuous autocorrelation R _ { ff } ( \ tau ) is most often defined as the continuous cross-correlation integral of f ( t ) with itself, at lag \ tau.
