The theory on chi-square statistic and the results of some simulation studies are reviewed and the methodological consequences are discussed. Several goodnees-of-fit indices are discussed and their employment in fit assessment and in the selection between competitive models are taken into consideration. A Monte Carlo study was used to point out the difficulties connected with model selection in SEM under misspecification. Keywords: structural equation models, LISREL, fit assessment, competitive models, misspecification. ER -
