Ward Fordham University Generalizability theory and common factor analysis are based upon the random effects model of the analy sis of variance, and both are subject to the factor inde terminacy problem: The unobserved random variables (common factor scores or universe scores) are indeter minate. factor indeterminacy definition
Factor score indeterminacy (FSI) is a wellknown phenomenon in Factor analysis. Since IRT can be conceived as factor analysis with categorical indicators, the same phenomenon must be present in
Factor indeterminacy definition free
A latent factor is a novel variate constructed from the manifest variates (measured variables) included in the factor analysis. In the principal component model each factor, referred to as a component, is uniquely constructed and considered determinate in nature.
factor indeterminacy issue; (2) to fill in the gaps in Wolfle's his torical record; and (3) to reassess the whole trend of the events of the 1930s in light of current developments in psychometrics.
Although the computation of factor score estimates is also possible for confirmatory factor analysis (CFA) and specific methods have been developed for this purpose (Beauducel& Rabe, 2009), most applications and discussions of factor score indeterminacy
Factor indeterminacy 211 conditions provides identification of exactiy one model solution. But the notion of 'identifying' something, model solutions in particular, is obscure.
Thus, we've just observed the indeterminacy of factor values. Factor can be determined in FA up to its loadings and its variance only; a infinite number of solutions exist in regards to factor values, true factor values will always remain under question.
the problems of factorscore indeterminacy, The point can be made that none of these problems bear on the practical utility of factor analysis as a research tool as long as it is used to study the structure of variables without attempting to estimate a person's factor scores (p. 89). In Bias, I specifically stated that if we wish to obtain
Indeterminacy, in philosophy, can refer both to common scientific and mathematical concepts of uncertainty and their implications and to another kind of indeterminacy deriving from the nature of definition or meaning. It is related to deconstructionism and
