In short, you use the PROC FREQ procedure to create a frequency table in SAS. For a simple frequency table, you only need to specify the input dataset with the DATA=-option. Optionally, you can add a TABLES statement and a variable name to create a frequency table of a specific variable.

How do you find the cumulative frequency in SAS?

How to Calculate the Cumulative Percentage by Group in SAS

2. You can use the PROC FREQ procedure in SAS to calculate the cumulative percentage per group.
3. You can use the DATA=-option to define the input dataset.

What is frequency missing in SAS?
