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:
Select Automated as the mode (if available).
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 .
