I am conducting a vignette experiment survey followed a between-subject, two-level (unethical consumption vs. ethical consumption ) in which each respondent judges only one single vignette. The dependent and independent variables are assessed according to the respondent judgement of the vignette. I would like to regress the dependent variable against the independent variables using Structural equation modeling. My question is how can i do the data analysis? Shall I analysis each level (unethical consumption vs. ethical consumption ) separately or can i combine them in one analysis.

Thanks in advance

Kind colleagues,

I am running a PLS-SEM on SmartPls 3.0. I specified the model as with two higher orderd formative components (HOCs). The lower order construcst instead have reflective causality (it's a reflective-formative HCM). To estimate it I tried with the repeated indicators approach and calculate the internal, convergent and discriminant validity statistics for HOCs by hand. Everything works fine except the overall model fit (which I know to be a very debated topic) that gives me SRMR above 0.11 and an infinite Chi-square (which I interpret as too many degrees of freedom and too tiny sample - 260). By using the disjoint two-stage approach instead, my model works perfectly. Not only the path coefficients are all significant, but also the overall model fit is amazing (SRMR below 0.06). My question is: does it make sense to consider these overall fit measure in the two stages approach? I mean, is it even comperable to a specification estimated with the repeated indicators approach? How should I choose the best model?

I need the help of the community!

Thanks everyone

I have some difficulties to understand the practical solutions for the collinearity problem in mediation analysis.

In my model I have collinearity problem between X and M. X explains about 86% of the variance in M with positive association between them. In the path analysis, X has positive direct relatiionship with Y. Contrary to my expectation, M has negative and significant relationship with Y. I guess this is becouse of collinearity. I guess my result is misleading and not correct. How can I solve this problem? In path analysis, can I test a mediation hypothesis without the direct relationship between X and Y to avoid collinearity problem?

Thank you in advance

Best regards

Hi. 

In following model, ABCD impacts E. E impacts F. F impacts G. H and I are moderators. In most studies impact of ABCD on E is measured by experiment and measured using ANOVA. Can I measure ANOVA and SEM together in single model?

I read that pls-sem does not have a universal GoF, although I came across a formula that was later criticized by other authors. So is there any alternative measure I can use instead, or is it really necessary to report any GoF measure for pls-sem? Thanks.

I have an enquete done for 2000 participants, I am not sure if I can use the new version of PLSSEM ?

In CB SEM, fitness indices include relative chi-square, GFI, AFI, CFI, NFI, TLI, and RMSEA. What type of Fitness indices should be considered in Smart PLS-SEM?

I want to see that to what extent my two independent variables Emotional Intelligence and Self-Efficacy effect/influence the dependent variable i.e. Teacher Effectiveness. For this, after my reading, I have concluded I should use Regression but again I' m confused that whether to use PLS Regression or SPSS? Also are PLS Regression & PLS-SEM same or different methods?

Thanks for viewing

As we know, the basic of doing PLS require us to identify direction of arrows among constructs and indicators. Anyone here give me an idea of my project?

For my case, I have 8 motivation factors, each factor has 5 survey questions (7-Likert scale). Purpose of the questions are to understand respondents' extent of satisfaction on each motivation factor. In SPSS, I transform -> compute the each of the 5 questions into each variable of motivation factor.  

Definitely, in PLS, motivation factors are CONSTRUCTS, while the 5 questions for each factor are INDICATORS.

From my readings, I think it is Formative, as the 5 survey questions will get me to know extent of satisfaction of each motivation factor.but my second supervisor commented it is Reflective.

Kindly share with me your point of view. Some good examples that will clear my odds for the rest of my life is much appreciating.

thanks

I am working on PLS-SEM. Can anyone help me out with the result reporting of the output of PLS-SEM?
