comment Evaluation of Alternatives
I have been out of this for a while, but I don't think f[a, f[b, c]] actually matches f[a,b,c]. It evaluates to it, and then it matches it. If you do f[a,b,c]/.HoldPattern@f[a,f[b,c]]:>post you also don't get a match

comment Entropy[…] doesn't calculate the entropy of a probability distribution? What does it do?
@becko, it's just what the function does, estimate the entropy from samples. Like Mean or Variance. However, those 2 also do the proper symbolic thing when passed a distribution and Entropy doesn't. But you can do it by hand, e.g, entropy[dist_] := Expectation[-Log[PDF[dist, \[FormalX]]], \[FormalX] \[Distributed] dist] ?
