Dear all,

Is it possible to include a constant term/intercept for each PLS regression equation in the structural model? If so, can anyone tell me how?

Many thanks,
Sandra

Hi Sandra,
SmartPLS works with standardized variables,
in this way the constants will be zero.

One idea is to copy/paste the unstandardized LV scores to Excel or SPSS and compute the regression there. The standardized results (betas) will be a little different from SmartPLS.

Best regards.

Hello,

It is understood that there is no constant in the standardized solution, but I would like to obtain the constant term to use with the raw regression weights that come from the IPMA procedure to create the full regression equation. How would I do that?

Thanks!

You should copy the undstandardized latent variable scores from the IPMA (IPMA > Latent Variables > Unstandardized) into SPSS, Excel or some other software that can run normal regression analysis.
You should get the same results for the path coefficients as in (IPMA > Path Coefficients > Unstandardized), but in addition you will also get the intercept.
