Predictive Relevance for formative measurement

[Tess]

1. Can we use Stone-Geisser's Q square to assess the model's capability to predict with formative endogenous latent construct?

Hi,

No. some literature PLS not recommend it.

Thanks for the reply.

If no, what other methods can we use to assess the predictive power of the structural model with formative endogenous variable?

Akter & Ambra (2011) mentioned that GOF can also be used to determine the overall prediction power of large complex models and is applied for both reflective and formative measures. But formative measures does not have the AVE values that were needed to calculate the GOF. So how would I go about that?

Thanks.

Hi,

First, some literature PLS no recommend for used formative endogenous construct.

Second: You can compute GoF and GoF relative for formative construct check Espozito Vinzi et al. (2010, p. 58-59) Handbook PLS.
