How to make different validation automatically using JMP script in standard least square regression?

    How to make different validation (training and validation) automatically using JMP script in standard least square regression?

    I want to do standard least square regression for 1000 times and every time with a new validation. And I do not know how to do this automatically by writing a script.

    I know that, for example, in predictive modeling Neural Networks we can write---- Validation Method ("Holdback", 0.1). But I do not know how to do this in Least Square Method.

    If I choose a fixed validation column, in the regression analysis's script, there would be these lines:
Where( Format( :Validation ) == "Training" )
Where( Format( :Validation ) == "Validation" )

 

Re: How to make different validation automatically using JMP script in standard least square regress

Are you using JMP Pro?  Its likely if you are using JMP to build a validation column, and using the validation role in a platform.

 

If I were you, I would right click on the statistic I wanted to bootstrap, and then choose the bootstrap option from the bottom of the pop up menu.

 

or you could do it the hard way..

(this script has a JMP Pro functinon it it)
