The tables of eigenvalues and eigenvector for level 2 criteria and level 3 variables respectively were computed. The level 2 diagnostic criteria evaluation gives an eigenvector, k1, while the level 3 variables produce the eigenvector, k2. k1 combines with the column vector of level 2 factors to give the Diagnostic Factor Index for level 2 criteria (DFI1), while k2 combines with the column vector of the level 3 variables to give the Diagnostic Factor Index for level 3 variables (DFI2), as shown in (1) and (2). Fig. 4 shows the DFI1, while Fig. 5 depicts the DFI2
