Re: Individual Co-Effecient of Determination Values R2

We provide the f² statistic, i.e., the effect size in terms of explained variance. It calculates as (R²inlcuded - R²excluded) / (1 - R²included) Whereas R²exluded means the R² of the dependent variable, when the focal variable is excluded from the model. This is the more common statistic in this con...

Re: Mediator - multiple IV

Yes, you should not use Sobel, but only the T and P values from the bootstrapping for the indirect and direct effects. SmartPLS2, however, does not report the results for indirect effects, but only for direct and total effects. Thus, you have to use either SmartPLS3, which gives you all necessary re...

Re: Mediation: negative or positive coefficients?

I would also think that an absolute value is more what you want to model for the mediator ("Asymmetry in Fairness Perception"), because any deviation from 0 indicates an asymmetry (both to the positive and negative side). Maybe there is no effect of fairness asymmetry? You may also think a...

Re: Bootstrapping - seeing the bootstrap estimates

If you have the bootstrapping result and you click an Path Coefficients, for example, you have 4 different results tabs:
  • Mean, STDEV, T-Values, P-Values
  • Confidence Intervals
  • Confidence Intervals Bias Corrected
  • Samples

Re: Mediator - multiple IV

You need to assess the indirect effects for significance. You do not need to delete your mediator. If only your indirect effect is significant: full mediation. If both your indirect and direct effect are significant: partial mediation. If only your direct effect is significant and not the indirect e...

Re: 3-Way Interaction of Moderation

You do not want to standardize any of the product terms. So it would be just: Standardize(A) x Standardize(B) x Standardize(C) In SmartPLS3 we make sure that the product term LV is not standardized after multiplication. This, however, will only work for two-way interactions. If you do your caclulati...

Re: Bootstrapping - seeing the bootstrap estimates

You will always find all estimates (path coeffcients, weights, etc.) for all n estimations in the "Samples" Dialog.

Re: Multigroup analysis - group sizes

They need not to have the same size, but it would be better if sample sizes are not very disimilar. There might be problems that results from unequal sample sizes across groups and confound your results. You find some further explanations in the book on PLS-SEM Hair, J.F., Hult, G.T.M., Ringle, C.M....

Re: PLSc loading in reflective model higher than 1

PLSc makes the assumption about appropriate factor models (reflective models). It takes these assumptions very seriously. It always produces strange results if the model is bad or assumptions are not met. Unlike CB-SEM, which does not give you results or bad fit, it will provide results, but these m...

Re: moderating effect (smartpls 3)

No. A moderating effect in PLS has a normal p-value from bootstrapping. Your effect is only significant if p is low (e.g. <0.05), but not if it is high.

Re: IPMA negative importance

Generally, negative importance makes sense, because the importance is based on the measurement and structural weights. If any of them is negative, you may have negative importance and the predictor is negatively related to your outcome. (You have to judge yourself if this makes sense in your specifi...

Re: Negative path expected -- but positive

Do you observe negative weights? It could happen, that if weights are negative the construct is in fact reverse coded compared to the indicators. Hence, a positive relationship between constructs might occur. Setting the initial weights to be negative might circumvent this problem. It is not cheatin...

Re: MGA results vs Groups bootstrapping

The difference between significant and nonsignificant might iftself be not significant. You can finde many paper about this phenomenon.
Important is only the significance of your difference test and not whether there are differences in significance within your groups.

Re: How to setup Smartpls3.0

Beside the fact that a basic model with correct settings should give you the same results in both Smart 2 and 3, some results are different in SmartPLS 3 as they were wrong in SmartPLS2. Some things were you might get different results, but should trust SmartPLS3: - Interaction and Quadratic Effects...
