### R^2 and Q^2

Why my R^2 and Q^2 values exactly same? (I used second-order construct with reflective dimensions)
Is Predictive relevance (Q^2) is applicable to second-order construct (with reflective dimensions),

Hi,

R^2 & Q^2 have same purposes for predictive models. So, the result both not different.
You know, If you have simple model, one exogenous and one endogenous variables, the result f^2 = q^2 = R^2 = Q^2 OK.

Hi,

Not reference mention that. This is my experience and it's true. Yes, Q^2 can applicable in 2nd construct (molecular).
