The first time you click Go in the Model Launch control panel (Figure 6.7), the Validation Method panel is removed from the Model Launch window. If you specified a Validation column or if you selected Holdback in the Validation Method panel, all model fits in the report are based on the training data. Otherwise, all model fits are based on the entire data set.
If you used validation, three reports appear:
• Model Comparison Summary
• Cross Validation Report
• NIPALS (or SIMPLS) Fit with <N> Factors
If you selected None as the CV method, two reports appear:
• Model Comparison Summary
• NIPALS (or SIMPLS) Fit with <N> Factors
To fit additional models, specify the desired numbers of factors in the Model Launch panel.
