Number of PLS Components

Use this option to specify the number of PLS components to compute.

In addition, if you specify a cross validation option in the PROC PLS Options field, you can also use this feature to specify the maximum number of components. For example, if you specify CV=ONE as a PROC PLS Option, then the number of components is computed using leave-one-out cross validation with a maximum equal to the number that you specify here.

To Specify the Number of PLS Components:

8

Select Automated as the mode (if available).

8

Either type the number of PLS components that you want in the text field or move the slider to the right or to the left to specify a value.

Tip: To change the scale of the slider, right-click on the slider and select Rescale Slider from the pop-up menu. Change the upper and/or lower boundaries in the window that appears, to rescale the slider and click OK.
