RANKTIE Function

ranks matrix elements using tie-averaging

RANKTIE( matrix)

where matrix is a numeric matrix or literal.

The RANKTIE function creates a new matrix containing elements that are the ranks of the corresponding elements of matrix. The ranks of tied values are averaged.

For example, the statements

   x={2 2 1 0 5};
   y=ranktie(x);

produce the vector

      Y
   3.5       3.5         2         1         5

The RANKTIE function differs from the RANK function in that RANKTIE averages the ranks of tied values, whereas RANK breaks ties arbitrarily.
