### View indirect and total effects in WarpPLS: YouTube video

A new YouTube video for WarpPLS is available; please see link below.

http://youtu.be/D9m4K_fv2vI

The video shows how to view and interpret indirect and total effects, as well as various related coefficients s (e.g., P values), calculated through a structural equation modeling (SEM) analysis using the software WarpPLS.

Enjoy!

Hi Ned,

How would you recommend I calculate direct and combined effects (controlling for the mediating variable) in WarpPLS?

Cheers,

Kim

Hi Kim. I think that the video clip below answers your question in reverse. It shows how a variable affects a mediating effect, and what happens when it is removed.

Thanks Ned. I think I get what you're saying. As for the combined effect, what would I be looking at in the output? I guess I'm looking to see if the combined effect becomes NS (complete mediation) or is reduced (partial mediation).

Cheers,

Kim

Hi Kim.

Let us say you have a simple mediated model with the following links: A > B, A > M > B.

If A > M > B is significant, and A > B is not, then you have full mediation.

If A > B is significant, then you have partial mediation.

These would assume that the total effect of A on B is also significant, in keeping with the classic condition proposed by B&K.

Awesome. Thanks Ned!
