SymKL.Plugin {EntropyEstimation} | R Documentation |
Returns the augmented plugin estimator of Symetrized Kullback-Leibler Divergence. See Zhang and Grabchak (2014b) for details.
SymKL.Plugin(x, y)
x |
Vector of counts from first distribution. Must be integer valued. Each entry represents the number of observations of a distinct letter. |
y |
Vector of counts from second distribution. Must be integer valued. Each entry represents the number of observations of a distinct letter. |
