The components Minitab displays depends on whether you perform cross-validation. For more information, go to Cross-validation in PLS regression.
If you do not perform cross-validation, Minitab displays the number of components that are calculated. This is the number you specify. If you don't specify a number, it is 10 (default) or the number of terms, whichever is less.
If you perform cross-validation, Minitab displays the following:
- The number of components to evaluate. This equals the maximum number of components you specify or, by default, 10 components or the number of terms, whichever is less.
- The number of components selected by cross-validation, based on the model with the highest predicted R2.
