TiedRank Command

TiedRank( <List> )

Returns a list, whose i-th element is the rank of i-th element of the given list L (rank of element is its position in Sort(L)). If there are more equal elements in L which occupy positions from k to l in Sort[L], the mean of the ranks from k to l are associated with these elements.

Examples:

  • TiedRank({4, 1, 2, 3, 4, 2}) returns \{5.5, 1, 2.5, 4, 5.5, 2.5}.

  • TiedRank({3, 2, 2, 1}) returns \{4, 2.5, 2.5, 1}.
