Entropy

Entropy[list]
gives the base information entropy of the values in list.

Entropy[k, list]
gives the base k information entropy.

  • Entropy[string] computes the information entropy of the characters in string.
  • Entropy can handle symbolic data.
  • With the option setting SameTest->f, Entropy[list, ...] applies f to pairs of elements in list to determine whether they should be considered equivalent.
  • The default setting for SameTest is SameQ.
