I have the following prog:
if idiiorisk ^= .;
what does idiorisk^= .; mean?
(for your info idiorisk = log ((1-_rsq_)/_rsq_) (rsq=r square))
if idiiorisk is not missing
View solution in original post
it means if idiiorisk is not equal to .(dot) since numeric field in sas is represented as dot for missing value
