Hi all, When I run the following code: proc glimmix method=laplace data = work.April;         class site plot YEAR WDENS;         model BAIS = DLG /solution dist=poisson DDFM=BETWITHIN CL alpha=0.1;         random intercept /subject=site TYPE=vc; Run; I get the error: ERROR: Variable DLG should be either numeric or in CLASSES list. The variable DLG is numeric, but there are missing values (".").  When I try the same code on the same variable with the missing values removed it works.  The problem is that the missing values are actually important, expecially when I have other models that are global.  Is there a way I can get this to work with the missing values still included? Thanks! ... View more
