Substitute in the values of ( a), ( b), and ( c). ( 4^2-4(4⋅ 1)) Evaluate the result to find the discriminant. ( 0) The nature of the roots of the quadratic can fall into one of three categories depending on the value of the discriminant( ( )): ( >0)means there ...
Furthermore, the square roots of AVE values exceeded the correlations between different pairs of constructs, and the heterotrait-monotrait ratio of correlations (HTMT) was below 0.85, confirming suitable discriminant validity. Conclusions The resulting instrument, due to its rigorous development and ...

We have chosen six dimensionality reduction methods (partial least squares, linear discriminant analysis, principal component analysis, RandomForest, ReliefF, and Extreme gradient boosting) and tested their efficacy on a hyperspectral data set of potato tubers. The extracted or selected features were ...

The results of the discriminant validity analysis confirmed the construct validity (Fornell and Bookstein, 1992) (see Table 4) by comparing the square roots of the AVE for each factor within the inter-construct correlations associated with that factor. In Table 4, the diagonal elements (bolded)...
(2017), construct reliability (including composite reliability (CR), Dijkstra-Henseler's rho (pA), and Cronbach's alpha (CA)) and validity (including convergent and discriminant validity) are good tools to evaluate the measurement model. As listed in Table 4, the Cronbach's alpha (CA) ...
