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 are ( 2) distinct real roots. ( =0)means there are ( 2) equal real roots, or ...
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 ...

The goal of LDA is to find the vector w that maximizes criterion function 𝐽(𝒘)Jw. In LDA it is assumed that all K classes have equal covariance. Following this assumption we can obtain the following discriminant function for k-th class: 𝛿𝑘(𝒙)=𝒙𝑻𝚺−1𝝁𝑘−12...

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) ...
