The RANK Procedure |
What Does the RANK Procedure Do? |
The RANK procedure computes ranks for one or more numeric variables across the observations of a SAS data set and outputs the ranks to a new SAS data set. PROC RANK by itself produces no printed output.
Ranking Data |
The following output shows the results of ranking the values of one variable with a simple PROC RANK step. In this example, the new ranking variable shows the order of finish of five golfers over a four-day competition. The player with the lowest number of strokes finishes in first place. The following statements produce the output:
proc rank data=golf out=rankings; var strokes; ranks Finish; run; proc print data=rankings; run;
Assignment of the Lowest Rank Value to the Lowest Variable Value
The SAS System 1 Obs Player Strokes Finish 1 Jack 279 2 2 Jerry 283 3 3 Mike 274 1 4 Randy 296 4 5 Tito 302 5
In the following output, the candidates for city council are ranked by district according to the number of votes that they received in the election and according to the number of years that they have served in office.
This example shows how PROC RANK can do the following tasks:
reverse the order of the rankings so that the highest value receives the rank of 1, the next highest value receives the rank of 2, and so on
rank the observations separately by values of multiple variables
rank the observations within BY groups
handle tied values.
Assignment of the Lowest Rank Value to the Highest Variable Value within Each BY Group
