Discriminant Notes Output Created Comments Input Data C: \Users\Student\Desktop\experiment for disciminant analysis.sav DataSet1 30 User-defined missing values are treated as missing in the analysis phase. 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.
