Hello,
What is the difference between the "correlation between the estimated regression coefficients (corr(b1, b2))" and the "correlation between the explanatory variables (corr(X1, X2))"? I found that, for example, corr(X1, X2) could be positive while corr(b1, b2) is negative. I think I understand corr(X1, X2), but I don't understand why we need to know corr(b1, b2), how it relates to corr(X1, X2), and how we can get those numbers from JMP. Thank you!
Try using Analyze> Multivariate Methods> Multivariate.
Throw all your factors and responses into the y role
