On The Robustness of Factor Analysis against Crude Classification of the Observations.

Olsson, Ulf

Multivariate Behavioral Research, v14 n4 p485-500 Oct 1979

The paper discusses the consequences for maximum likelihood factor analysis which may follow if the observed variables are ordinal with only a few scale steps. Results indicate that classification may lead to a substantial lack of fit of the model--an erroneous indication that more factors are needed. (Author/CTM)
