I think what you want to do (assuming you have JMP Pro) is just right click on the statistic that you want to bootstrap on (i.e. the RSquare the Cross-validation section of the Fit Model Report) and select Bootstrap. You can then choose the number of iterations and it will generate a data table and report of the results.Mon, 06 Aug 2018 13:59:15 GMThttps://community.jmp.com/t5/Discussions/How-to-run-standard-least-square-regression-1000-times-with/m-p/66601#M34461MikeD_Anderson2018-08-06T13:59:15ZRe: How to run standard least square regression 1000 times with different validations?

<P>Thank you for your reply. Yes I am using the JMP Pro. Sorry that I did not find the statistic used for bootstrap.</P><P> </P><P> </P><P>Here is my script: I just want to run this analysis for 1000 times using 1000 different validations. Thank you.</P><PRE>Fit Model(

<P>I’m not aware of being able to bootstrap via a command in JSL. The way I was proposing was through the GUI. You might have a look at the example under the Resample Freq heading in the scripting index for an idea about how to set it up.</P>
<P> </P>
<P>UPDATE - There is a JSL message function (search the scripting index for "bootstrap" to find it)... you learn something new every day!! LOL.<BR /><BR />M</P>Wed, 08 Aug 2018 00:31:37 GMThttps://community.jmp.com/t5/Discussions/How-to-run-standard-least-square-regression-1000-times-with/m-p/66651#M34470MikeD_Anderson2018-08-08T00:31:37ZRe: How to run standard least square regression 1000 times with different validations?
