Problem Note 43749: Incorrect or missing values in OUT= data set with full-rank coding and redundant parameters
If a full-rank coding (such as PARAM=REF) is used in the CLASS statement and if one or more parameters in the model are redundant (resulting in parameters with zero degrees of freedom), then the statistics produced by the LOWER=, UPPER=, STDRESDEV=, STDRESCHI=, DOBS= (or COOKD=), and LEVERAGE= (or H=) options are incorrect or missing.
To avoid the problem, use nonfull-rank coding by specifying the PARAM=GLM option in the CLASS statement.
