Also, HOW DO i tell sas to treat all of these variables as categorical?
In that case your covariates are many (more than 40). So it is the code not the data set that is the problem. However, "ERROR: There are no valid observations" seems like a basic syntax mistake somewhere. http://support.sas.com/kb/24/455.html One thing not clear to me is if this requires the PARAM=GLM which I normally don't work with or can be done with Effect or Reference coding as well.
Its not the number of cases relative to the variables that is the issue. I want to be able to test the return code fornon-zero return codes.Is there an option I'm missing that will make it ignore this type oferror? All rights reserved.
