Boosted Maximum Number of Iterations

Use this option to specify the maximum number of iterations for generating Gradient Boosting Trees.

For quantitative and binary traits, the number of iterations equals the number of trees.

For qualitative, non-binary traits, a separate tree is created for each trait category in each iteration.

To Specify the Maximum Number of Iterations:

Select Automated as the Mode.

Select Boosted as the Automated Model Type.

Either type the maximum number of iterations desired 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.
