Hello. I could not find the for the variable Non-mlanoma skin cancer= "cnskna."

Thanks

The "NIU" value label indicates an individual record is "not in universe". This means that the question was not asked to this person. In general, yes, it is a good idea to drop all NIU observations when performing analysis on a particular variable.
