### Q2

Posted:

**Thu Sep 07, 2017 3:52 pm**Dear friends:

In calculating the predictive relevance of an endogenous reflective construct, we must calculate Q2. In the book, Hair et al. (2017, p. 207) state that zero values and below have no predictive relevance. I ask: If Q2 is a square, can Q2 reach a value below zero? Is there something wrong or Q2 doesn't mean a square?

Best Regards
