  2. Create the Elect data set.
  3. Generate the ranks for the numeric variables in descending order and create the Results output data set.
  4. Create a separate set of ranks for each BY group.
  5. Create two new variables that contain ranks.
  6. Print the data set.

How do you rank numbers in SAS?

How to Rank Data in SAS

  1. Ranking Data.
  2. Using _N_
  3. Using RETAIN.
  4. Using PROC RANK. Ranking with Ties. Percentile Ranking. Ranking in Descending Order. Ranking Multiple Variables.

Can we use rank function in PROC SQL?

The descending keyword tells SAS to sort the data in descending order and assign rank to the variable accordingly. Suppose you need to split the variable into four parts, you can use the groups option in PROC RANK. It means you are telling SAS to assign only 4 ranks to a variable.

How do I create a quintile in SAS?

For example, you can create quintile groups by specifying GROUPS=5 in the PROC RANK statement. The variable named in the RANKS statement will contain values ranging from 0 to 4 for the groups in the output data set.

How do you create quartiles in SAS?

You use the QNTLDEF(PCTLDEF) option to set the method used by the SAS procedure to compute quartiles. The default method used by SAS, is QNTLDEF=5. Calculating Q1 (25th percentile) Firstly calculate np. n = 5 and p = 0.25.

What is the syntax of PROC sort?

PROC SORT DATA=auto OUT=auto3 ; BY DESCENDING foreign ; RUN ; PROC PRINT DATA=auto3 ; RUN ; You can see in the proc print below that the data are now ordered by foreign, but highest to lowest. It is also possible to sort on more than one variable at a time.

What does PROC RANK only 4 mean in SAS?

It means you are telling SAS to assign only 4 ranks to a variable. GROUPS=4 for quartile ranks, and GROUPS=10 for decile ranks, GROUPS = 100 for percentile ranks. Suppose you need to calculate rank by a grouping variable. To accomplish this task, you can use the by statement in proc rank.

What is the rank procedure in SAS?

If SAS doesn’t process a row with a new class, then 1 is added to the retained rank, namely the rank of the previous row. In the previous example, we showed how to rank your data by groups. However, we didn’t show how to deal with ties. With the RANK procedure in SAS, you can define how to process ties.

How do I use ties in PROC RANK?

With the ties keyword in PROC RANK, you can specify how to work with ties. There are four options: MEAN (default): Assigns the mean of the ranks to the new rank variable. So, in the example below, we have four times A 3 with ranks between 2 and 5.
