title: DESCRIPTIVE FACTOR ANALYSIS.
abstract: -When a set of variables cannot be regarded as being drawn from a well defined population, the estimation of communalities, population parameters, and universe factors is not a rational undertaking. A descriptive factor analysis can be performed by weighting test vectors inversely as the components of total test variance unable to determine a test battery common factor. Such components are well defined and a descriptive factor analysis based on weighting by such components requires no assumptions about the population and no estimations of communalities ; it requires only that regressions be reasonably linear.
