Given a column with a list of values, computes the Shannon Entropy for that set of values. The single measure version of this is:
ShannonEntropy = SUMX( SUMMARIZE( Entities, Entities[Entity], "H(X)", -1*COUNTROWS(Entities)/COUNTROWS(ALL(Entities))*LOG(COUNTROWS(Entities)/COUNTROWS(ALL(Entities)),2)) ,[H(X)])
There is a single input, a column, in this case called Entities[Entity].
