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 Statement 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:

Select Automated as the Mode.

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.
