I am working with a table that holds data on patient visits. There is a "Visit Date" column and the dates contained in it span over 6 years (Thousands of records).
I want to run a frequency distribution on the entire table but this gives me countless lines of output due to the variability of the dates.
What I am trying to do is to use PROC FORMAT to group the date output into 3 months each so that i can better read my data. Please is there a way this can be done?
