Number of Rounds of Selection

Use this option to specify the number of times to repeat the regression-based variable selection process.

When this number is greater than 1, the selection process is repeated after eliminating all variables that have already been selected in previous rounds according to the criteria that you have specified. This enables you to select multiple sets of predictor variables that perform well together as well as all good predictors that might be collinear. Variables from all rounds are then carried forward.

To Specify the Number of Rounds of Selection:

Select any option other than None as the Model Selection Method .

Either enter the desired value into the text field, or move the slider to the right or to the left to change the 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 .
