Missing Value Handling | Definition of Missing | User-defined missing values are treated as missing in the analysis phase. | |||||||||
Cases Used | In the analysis phase, cases with no user- or system-missing values for any predictor variable are used. Cases with user-, system-missing, or out-of-range values for the grouping variable are always excluded. | ||||||||||
