DiceDissimilarity

DiceDissimilarity[x,y]

gives the Dice dissimilarity between Boolean vectors x and y.

Details

  • DiceDissimilarity works for both True, False vectors and 0, 1 vectors.
  • DiceDissimilarity[u,v] is equivalent to (n10+n01)/(2n11+n10+n01), where nij is the number of corresponding pairs of elements in u and v respectively equal to i and j.
