picking random occurences

[deleted_user]

hi,

I have a situation where I have to pick limited number of occurrences in random way.

Ex: Out of 50 occurrences I have to pick only 30 occurrences in random way ( not the first 30)

How can I do that?

Thanks,
Sam

If SAS/STAT is installed, have a look at the surveyselect procedure documented in
