How to randomize a select number of individuals from different groups

boodaloo1 — Sun, 17 Jul 2016 13:31:57 GMT

I have a data set in which there are 700 patients represented from six clinics. All are characterized as noncritical, moderately critical, or severely critcal. I need to write a SAS code that will randomly choose 2 noncritical patients from each of the 6 clinics. I also want to put a statement in the coding that if there are fewer than 2 patients in any clinic, to select them all, but I am unsure how to write this?

Look into proc surveyselect instead of doing it manually.

The SELECTALL option allows you to specify that you should take all values from a clinic if less than 2.

Does the statement

I also want to put a statement in the coding that if there are fewer than 2 patients in any clinic, to select them all, but I am unsure how to write this?

mean that when there are fewer than two patients, you are willing to accept moderately critical, or severely critcal patients as well?
