Conflict in results PLS-MGA
Posted: Fri Sep 20, 2019 11:39 am
Hi everyone,
I conduct multigroups analysis with PLS-MGA for 2 groups A & B. The results show that :
Group A : path coefficient = 0.158, p = 0.006 (Sig.)
Group B : path coefficient = 0.063, p = 0.103 (non sig.)
Difference of coeff. = 0.095, p = 0.913.
Objectif is to see if there is significant difference in path coefficient between two groups, if yes, in which group the effect is larger.
According to instruction in Advanced issues in PLS-SEM (Hair et al. 2018), I see that (1-p-value) of the difference is < 0.10 (1-0.913), so the difference beetween 2 groups is significant and the path coefficient is larger in the group B than in the group A. However, for Group B : path coefficient is not significant (It means there is no relationship for group B) and it is lower than group A.
I have some questions about that :
1. Do we compare p-value to 0.10 or 0.05 to assess significant (I think it is 0.05 but why in the book the authors use 0.1) ?
2. Why there is a conflict in these results of path coeff. for group B and p-value of the difference ?
3. Can I conclude that the effect is larger in group B than in group A and there is moderation effect in that case ?
Could anyone advise me how to report these results and tell me where I'm wrong ?
Thank you so much.
Regards,
