Two models : Comparison based on path coefficient and R²
Posted: Thu Jul 05, 2018 2:22 pm
My question is related to the PLS approach ,and I can rephrase it as follows:
If I have 2 PLS models (developed with the same data set):
-The first model contains two latent variables: A1 and B.
-The 2nd model contains two latent variables: A2 and B (the same B of the model 1).
- Both models show that A1 and A2 have a positive and significant effect on B ( Path coefficient> 0.1 and t> 1, 645, One-tailed (Using Bootstrap).
I now want to show that the effect of A1 on B is greater than the effect of A2 on B
-By comparing the 2 models we find that:
- [Path coefficient of A1 => B (model1)=0,573 ] > [Path coefficient A2 => B (model2)= 0,398]
- [R² of B (model1)=0,328] > [R² of B (model2)=0,158]
With this comparison (based on the path coefficient and R²) can we conclude that: "the effect of A1 on B is greater than the effect of A2 on B" ?
If no, how can I demonstrate it?
