(a) Power to detect association (defined as the proportion of tests significant at an α of 0.05) under multivariate backgrounds a, b and c, for association models 2–6 (described in Table 2). In each case power is shown for the Combined multivariate approach (CMV) and for univariate analyses of the sum score (SS), Regression factor score (RFS) and Bartlett factor score (BFS). (b) Power to detect association under multivariate backgrounds d, e and f, for association models 2–6. (c) Power to detect association under multivariate backgrounds g, h and i, for association models 2–6.
