a *, P < 0.01; **, P < 0.001; ns, not significant; 2FI, two factor interaction;
Qua, quadratic.
F-test for significance of adding the quadratic terms to the 2FI model.
bComparison of residual error to pure error from the replicated center points.
c t-tests, whether the respective coefficient is different from 0 (H0: coefficient = 0 vs. HA: coefficient ≠ 0).
