Create and use second order latent variables in WarpPLS: YouTube video

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

http://youtu.be/bkO6YoRK8Zg

The video shows how to create and use second (and higher) order latent variables with the structural equation modeling (SEM) analysis software WarpPLS.

Enjoy!

thank you Prof for second order construct video. basically in my research I am using four dimensions with various items. All items fulfill accepted criteria of >0.5. But when I put these four dimensions in a second order construct than among four one construct load below .5. kindly suggest me a salutation.

Second order LVs often end up being multidimensional, with non-redundant indicators – and thus low loadings. As such, they should pass formative measurement criteria, as opposed to reflective criteria. I hope that the materials linked below can be of use in connection with this.
