Re: Reflective-Formative HCM | Discriminant Validity HTMT

Hi Chris: I would advise you not to use the repeated indicator approach because of issues that arise of artificially correlated residuals (see Becker et al., 2012). Instead I would use the two step approach and first estimate the latent variable scores of your first-order construct in a fully specif...

Re: Endogenous construct with formative form

Hello, there is an ongoing discussion about formative (endogenous) variables (see all papers on https://link.springer.com/journal/13162/3/1/page/1). In my opinion, from a theoretical point of view it is difficult to find good arguments for formative endogenous variables. See also: John W. Cadogan, N...

Re: measurement model validation in a scientific paper

Dear PATR: Of course, you can test measurement invariance between genders to convince yourself. However, for gender I would not report it in the paper only if it is requested by a reviewer. There are so many aspects, even the educational or social background, the job position, the age etc. of your r...

Re: PLS-POS Result interpretation

Dear olearus, for me your interpretation sounds legit. The very small group could be interpreted as outliers. If you increase the number of segments in FIMIX-PLS or PLS-POS you force each observation into the number of pre defined segments. As noted in 2. the sample size could become too small for e...

Pre-Segmentation in PLS-POS

Dear SmartPLS developers: I've got a question regarding the pre-segmentation option in PLS-POS. The following information is given within the notes: "If this option is selected, the algorithm will perform a pre-segmentation in the first round that assigns all units to its best fitting group accordin...

Re: How to test moderation of multi-answer categorical varia

I would not recommend using interaction terms for categorical variables as in your case. Instead, you could use MGA to investigate categorical moderator variables. Moderation analysis with interaction terms from my point of view only makes sense for binary variables or ordinal scaled variables from ...

Re: NEED FOR FIMIX PLS TEST

PLS-MGA is merly able to capture observed heterogeneity, i.e., group variables that are already known and which might explain differences in the path coefficients by already existing theory. FIMIX-PLS accounts for unobserved heterogeneity. Thus you should also apply methods such as FIMIX-PLS or PLS-...

Re: New rules for keeping formative indicators

Dear Mr. Aljabr: 1. Assuming that you do not have any multicollinearity problem as described by Dr. Becker, I use the following common example of drunkenness to provide a possible interpretation for insignificant regression weights. You could measure drunkenness formative as the extent to which you ...

Re: Multigroup analyses

Dear Mr. Koch: The level of significance should be set on the basis of your target journal. 5% is more conservative but there are also journals that accept higher levels up to 10%. The setting in SmartPLS is primarily for calculating the confidence intervalls. You can see the change in the output re...

Re: Measurement Invariance

Dear Ten Yes, it is sufficient to confirm both configural and compositional invariance in order to conduct PLS-MGA. When both are established, PLS-MGA can be performed with standardized variable scores each per group. Since PLS commonly works with standardized scores there are no further steps neede...

Re: The two-step approach to model 2nd order constructs

Dear Ms. Barouni, you can find path model depictions for each approach in Becker et al. (2012, pp. 380-382). For the two stage approach there is also the possibility to combine it with the repeated indicator approach in the first step (Ringle et al., 2012, pp. 6-7). Best MJ Becker, J.-M., Klein, K.,...

Re: Formative Model Identification

Dear Ms. Rodrigues A construct in PLS is identified irrespectively whether it is estimated using mode A or B when there is at least one more endogenous or exogenous latent variable, i.e., the 'two or more dependents' identification rule won't be necessary (see Becker et al. 2013). However, I would r...

Dear AAljabr I have already asked myself this question a few days ago. The following is my understanding from reading the literature and trying out some stuff. Mode A and Mode B lead to quite similar results when sample size is high (Becker et al., 2013, p. 16). I have tried it with different sample...
