Figure 32.16 shows the transformations that are available when you select from the list. The rank transformation of a variable Y is a new variable that contains the ranks of the corresponding values of Y.

There are actually four different rank functions, depending on the options you select on the second page of the wizard. (See Figure 32.17.) If you select as the Rank of Ties option, then the SAS/IML RANK function is used to compute ranks. If you select , then the SAS/IML RANKTIE function is used. This is summarized in Table 32.6.
