Mixture Modeling with Training Data
ERepeat the preceding steps for the PossiblyVersicolor group, but this time double-click
versicolor in the Choose Value for Group dialog box.
ERepeat the preceding steps once more for the PossiblyVirginica group, but this time
double-click virginica in the Choose Value for Group dialog box. The Data Files dialog
box will end up looking like this:

ESelect Assign cases to groups (a check mark will appear next to it). The check mark tells
Amos to assign a case to a group whenever the dataset does not specify which group
that case belongs to.
