Two approaches were identified as a potential remedy of the problem. One is based on the idea of Williams (2007) introducing a (spurious) mean structure to the CFA model, supplying more information to the estimation process. Another is to introduce a random intercept factor that is orthogonal to the factors in the current CFA model (Maydeu-Olivares & Coffman, 2006), consuming more information in the estimation process. Rationale and effectiveness of these two contrasting approaches will be examined with simulated data and empirical data. キーワード: confirmatory factor analysis, MTMM, identification, method factor △▼△▼△▼△▼△▼△▼△▼△▼△▼△▼△▼△▼△▼△▼ 足立浩平 (大阪大学)
