Hi, I'm working with a dataset where some of the variables have only missing values associated with them. From this dataset, I would like to completely drop all of those particular variables. Is there a way to do this, or do I have to deal with each variable individually? I'm working with over 300 variables, and about 200 of them are the ones I want to drop, so doing a keep statement for the 100 other variables will still be way too time-consuming. I know I can do if variable=. then delete to get rid of my missing values, but I don't know how to tell SAS to get rid of all the variables that don't have any values associated. Help would be greatly appreciated!! Thank you!
