The idea of a second order model is interesting, but I'm not sure of the interpretation of it. I've been reading through posts in the forum, but I need to do some more research on this topic. Is there a good article you can suggest that may clear this up for me? Thank you, Westley Ritz Unfortunatel...

Re: FIMIX PLS
I would like to ask how to use the membership probabilities obtained after using FIMIX in order to run a post hoc analysis. I read Hann´s book and it is not clear to me. From my point of vie there are two choices: A) weighting each descriptive info of each case by these probabilities and running th...

I was handed the model and asked to relipcate it in PLS It's either a) a test b) the person who asked you to run it doesn't understand PLS or c) if it was claimed to be estimated originally via PLS then the person/organization that originally ran it lied. But, the model that you describe sounds lik...

Re: Mapping LVs to another LV without Indicator Variables
I have a model where I need 2 or 3 latent variables (each with their own indicator variables) to go into another latent variable that does NOT have any indicator variables. I spent some time playing with SmartPLS trying to figure this out but I haven't found a solution. Does anyone know how to do t...

Re: Incoherent Graph
Hello, I am in the process of creating a very simple PLS model with 2 formative LVs (each with 4 observed variables) loading on 1 reflective LV (with 3 observed variables). I expected the LVs to turn from Red to Blue after connecting them, but they have not changed and I get an error message indica...

Re: Path elimination
...to the method of eliminating insignificant paths (t-value<2 as indicated by the bootstrap algorithm). Successively eliminating insignificant paths works well and leaves me with the significant ones whose influence on service quality I can then interpret... Unfortunately, I suspect that you're al...

Re: Number of indicators
bootstrap t-values of the paths from the first order benefits to the second order service quality construct are below 2 (sample size 500). At the samw time, the R square for service quality is high and other quality criteria (communality, redundancy, cronbach alpha, etc.) are also acceptable. The p...

Re: Re-use of indicators for second order construct
Hello, thanks for your post. I am facing exactly the same problem. For both of you, do you have alternative measures for the scales you are developing? If so, create your models with those as the dependent variables. If you lack known alternatives, then what other variables are your factors thought...

Re: effect size negative?
But i was confused, because i got a higher R-square for D without the path B to D. Of course, my effect size was negative. Hi Michael, In PLS, the computation of constructs is not independent of the paths in the structural model, so as you add/remove structural paths it's not as if the values of th...

Re: proper methode for 2nd order constructs??
She has one higher construct in her model, which contains 5 dimensions. She defined, that the 2nd order construct was formative and 4 1st order constructs were reflective (1 formative). Then she did an exploratory factor analysis with the reflective 1st order constructs and choose the indicators wi...

Re: error correlations
I also have a doubt. In PLS no error terms are mentioned explicitly. What happens if two error variables are correlated? This will falsely show a significant path between two variables, even though only their errors are related. I think that's not correct. It's not that error terms aren't explicitl...

As I said, conceptually (theoretically) I understand that the 3rd order factor might be necessary. I have have been wrong about the computational necessity, my mind thinking about it in covariance modeling terms. How to do it? Treat the 3rd order factor the same as you would a second order factor, w...
