How to add error terms

Post by vk7882 » Tue Sep 02, 2014 11:44 am

Hello everyone,

I am conducting an SEM with Smart Pls for the first time and as far as I know I have to add error/disturbance terms to the latent variables. But how do I actually do this? I have only read about it, but have never seen an error term in a graph, nor have I read about how to add an error term in applicational texts about SEM in Smartpls.

Best,
Vanessa

Hi,

PLS and LISREL have different filosophy, in PLS error in equation but in LISREL error in latent variables. You must understanding it first. If you need to know error in latent variables my be you want to calculate 1-loading factors = error.

and that is why reliability should be generally much higher in PLS.

I think the low rules of thumb of 0.7 are antiquated for PLS

How to Measure Error in a Model
For example, I have equations for inner model:
η1 = 0,613 ξ1 + 0,201 ξ2, R2 = 0,804
η2 = 0,215 η1+ 0,451 ξ1 + 0,795 ξ2, R2 = 0,807
How do I measure the error in a model (ς) in PLS? Thank you.

Regards,

Erwin
