What does Proc rank do in SAS?

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.

How does Proc rank work?

The RANK procedure (PROC RANK) is useful for ranking numeric variables in a data set across observations. You often see PROC RANK used to rank data into quartiles, deciles, or percentiles. This action requires that you use the GROUPS= option in the PROC RANK statement.

How do you rank in SAS?

First, we order our data set by the group (class) and then by the variable to rank (score). With the BY statement, the FIRST keyword, and a simple IF-THEN statement we assign a value of 1 to our new variable rank if SAS processes a row with a new class.

How do you rank a group in SAS?

Program

  1. Set the SAS system options.
  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.

What is Proc univariate in SAS?

ABSTRACT. PROC UNIVARIATE is a procedure within BASE SAS® used primarily for examining the distribution of data, including an assessment of normality and discovery of outliers.

Does Proc mean missing values?

PROC MEANS excludes missing values for the analysis variables before calculating statistics. If a class variable has a missing value for an observation, PROC MEANS excludes that observation from the analysis unless you use the MISSING option in the PROC statement or the CLASS statement.

What is Proc Tabulate used for?

Proc tabulate is predominately used to make nice looking tables. Unlike proc freq this procedure can handle multiple variables in the row and column expressions. It can also handle multiple levels in both rows and columns whereas proc freq will only create two variable contingency tables.

What is the purpose of the PROC univariate procedure?

PROC UNIVARIATE is a procedure within BASE SAS® used primarily for examining the distribution of data, including an assessment of normality and discovery of outliers.
