I know SmartPLS reports the standardized regression coefficients, but does anyonw know where or how I can get the unstandardized ones?

Dear Prof. Eleanor,
When runing the PLS algorithm choose Original Data instead of Mean 0 Var 1;

My question is: Since you choose Mean 0 Var 1, is it possible to have weights greater than one?

If you chose original data the path coefficients will still be standardized. Standardization of the latent variables is always done during the algorithm. Only the outer approximations are different. See also (Lohmöller, 1989) or (Tenenhaus et al. 2005).

If you want the unstandardized path coefficients you should use the unstandardized LV scores from the section “Index Values”. However, currently there is a bug in the calculations of those values so that I would recommend calculating them by hand.

Hello
I'm wondering if the bug in the calculations for unstandardized coefficients has been fixed?
Thanks, Jenni
