Hi Mark,
Thanks for your reply!
When we set the random seed, are we determine the way for cross validation?
When I set the random seed to 1 and get a model, I would get one "go" option on the top "model lauch". After I click the go, another model with slightly different R^square is obtained. What is making the difference of the model R^2 compared with the previous one when I click on "Go"?
If I do not specify the random seed and click on "Go", will it give us different models with different random seed?
Thanks!
