# RussellRaoDissimilarity

 RussellRaoDissimilaritygives the Russell-Rao dissimilarity between Boolean vectors u and v.
• RussellRaoDissimilarity is equivalent to (n10+n01+n00)/Length[u], where is the number of corresponding pairs of elements in u and v respectively equal to i and j.

The elements can also be True and False:
