I am running a GLM model (Poisson with Log link function) and in the case processing summary 5 cases are being excluded (see below). There are no filters on and no missing data. Why would these cases be excluded?
Case Processing Summary
N Percent
Included 7946 99.9%
Excluded 5 0.1%
Total 7951 100.0%
For the dependent variable,
"If a data value is non-integer, less than 0, or missing, then the corresponding case is not used in the analysis."
