How can I get the predicted R2 with JMP ?

[#1]

Comment puis-je obtenir le R2 prévu avec JMP ?
J’ai réalisé un design de surface de réponse avec trois facteurs. J’ai obtenu le R2 ajusté et j’aurais besoin du R2 prédit pour valider mon expérience.

Hey @Cedrick1 I believe this is what you  are looking for

First, R^2 does not validate your experiment.  It is one estimate to help you evaluate your model.  The better use of R^2 is to compare the R^2 to the Adjusted R^2 to see if you have over-specified the model.  The only time I have seen predicted R^2 is with Minitab.  Minitab takes a random sample from the data set and uses the model you have entered to calculate how much of the variation in that data is explained by the model.  Whether this is actually useful ...?

There are many ways to "hold out" some data from a data set (e.g., boot strapping, nearest neighbor).  Use the rest of the data to estimate the model and then test the model with the data that was held out.  Is this what you are asking?
