Example 4: Cross-Distribution Entropy w/ Different Binning Methods
Import a signal of pseudorandom integers in the range [1, 8] and calculate the cross-
distribution entropy with an embedding dimension (m
) of 5, a time delay (tau
) of 3,
and Sturges’ bin selection method.
X = ExampleData('randintegers2');
XDist = XDistEn(X(:,1), X(:,2), 'm', 5, 'tau', 3)
>>> Note: 17/25 bins were empty
XDist = 0.5248
Use Rice’s method to determine the number of histogram bins and return the probability
of each bin (Ppi
).
[XDist, Ppi] = XDistEn(X(:,1), X(:,2), 'm', 5, 'tau', 3, 'Bins', 'rice')
>>> Note: 407/415 bins were empty
XDist = 0.2802
Ppi = 1×8
