Abstract: In the currently prevalent model of factor analysis (FA), specific factors and errors are not dissociated, though they had been separated in the original conception of FA. Thus, an FA model with specific factors dissociated from errors is considered, whose least squares procedure is referred to as comprehensive FA. The main goal includes showing that the model part of comprehensive FA and residuals are identifiable, common and specific factors are undetermined but have some constancy, and comprehensive FA has clear relationships with principal component analysis.
