Dear Christian,

I would be very grateful if you could explain why the jackknifing is obsolete in PLS or where I can read about this? Could jackknifing better help to deal with influential observations?

Regards,

Katja

Good afternoon, Unfortunately, I have a similar problem. I already tried orthogonalizing, but moderating effect is still negative. Is there any other way to deal with suppression? And could you please elaborate on two-step approach you mentioned in the previous comment? I did not really get it relat...

Dear Christian,

Thanks for your reply! It worked very well. Did you mean A Primer on Partial Least Squares Structural Equation Modeling (PLS-SEM) when you talked about Hair et al. (2013)?

Greetings,

Katja

Dear Christian, Thanks for your fast response! I've read in Preacher and Hayes (2008) that confidence intervals should be reported. If so, for the calculation of CI (1) should I take a original sample parameter estimate and the corresponding standard error (not the ones from resampling) and (2) can ...

Thanks for helpful tips. One more question, I have calculated a t-value but how do I define if the effect is significant?

Would appreciate your response.

GoF for the model with formative and reflective constructs

Dear all,

I had a question about GOF. Is the formula proposed in TENENHAUS et al. (2005) also suitable for the model that include both formative and reflective constructs?

I would appreaciate your response!

Principle component analysis for reflective scale before PLS

I have a question concerning reflective measures in PLS. I'm trying to construct a reflective scale. I thought about the procedure in PLS as similar to Principle Component analysis. My colleague, who took PLS course, suggested me to run a PCA first on my data before starting analysis in PLS. Then in...
