Abstract
Many authors suggest that conditions originally presented by Howe (1955) and later by Jöreskog (1979) are sufficient to identify confirmatory factor analysis models. In this note we show that these are sufficient conditions for unique factor loadings under rotation but they are not sufficient for model identification. This is demonstrated with an extended example.Keywords
