Hi Namhyun,

You can find this in any statistical reference/textbook, not necessarily PLS reference.

Hi all, Thank you very much for this interesting conversation. I found it very helpful. Regarding noone's question, I am facing the same problem with my second order construct (dependent). I obtain R2 = .99 and the path coeficient = Zero. I found this article (Ringle et al. 2012/MISQ) interesting an...

Hi Ismail, The Sobel test takes following formula: z-value = a*b/SQRT(b2*sa2 + a2*sb2). This formula requires; a = the raw (unstandardised) regression coefficient for the association between independent variable and mediator, sa = the standard error of a (the relationship between the independent var...

Dear Mr Dennis, Thanks a lot for your contributions on R2 and GoF. They is really helpful and save a lot of time!! I have a second order formative construct which is formed of two first order formative constructs. I run algorithm, and R2 for the two first order constructs is Zero; and for the second...

Hi all, I found the formula for calculating Composite reliability: Henseler et al. (2009) p.300 I checked using various examples in published papers; i.e. Wetzels et al. 2009, p: 188; and it worked for calculating Cr for second, third and fourth order constructs. However, AVE for second, third, four...

Hi all, I am confused from all the posts regarding Communalities, loadins, AVE - for MV, Latent variable!!! I am working on a model: my Independent variable is a 3rd order reflective construct - which includes four 2nd-order constructs. Each 2nd order construct includes two 1st-order latent variable...

Third Order Construct

Hi all, My Model involves two high order constructs: The Independent is a Reflective 3rd-Order construct and the dependent is a formative 2nd-order construct. I would like to run algorithm to check the validity and reliability. My question is: shall I run the whole model with the independent and dep...
