Factor analysis is a technique that purports to explain observed relations among several variates in terms of ampler relations that provide insight into the underlying structure of the variates. The analysis, however, is technically underdeveloped, and its usefulness for studying interrelated hydrologic variates is questionable because of the inherent indeterminacies in the factor model, the lack of knowledge about the sampling properties of the factor loadings, the fact that the factors are not directly observable, and the inability to use the results of factor analyses in other analytic studies.
