...Such statedependent behavior is a defining hallmark of complex nonlinear systems (3, 4), and nonlinearity is ubiquitous in nature (3–11)....

...Note that CCM is related to the general notion of cross prediction (3, 25) but with important differences....

...In more detail, CCM looks for the signature of X in Y’s time series by seeing if there is a correspondence between the “library” of points in the attractor manifold built from Y, MY, and points in the X manifold, MX; these two manifolds are constructed from laggedcoordinates of the time series variables Y and X respectively (3, 19, 24) (movies S1 and S2)....
[...]
...This enables us to estimate states across manifolds using Y to estimate the state of X and vice-versa using nearest neighbors (3)....

...This means that each variable can identify the state of the other (3, 19, 20, 24, 25) (e....
