Table 3.

Standardized loadings (pattern matrix) derived from the correlation matrix for the three components (RC1, RC2, and RC3), obtained through Principal Component Analysis with orthogonal Varimax rotation of the loading matrix are reported (see main text for further details). Primary loadings greater than ± 0.50 for each component are shown in bold. The component communalities (i.e., the proportion of variance in each index variable that is accounted for by the components) are shown in column “h2”. Each component's uniqueness (i.e., the amount of variance in each variable not explained by the components, or 1–h2) are shown in column "u2". Hoffman's index of complexity for each index variable (i.e., the number of latent components required to account for the variance observed in those variables) are shown in column "com".
