Factor Analysis of Dichotomized Variables
Peer reviewed Peer reviewed
Christoffersson, Anders – Psychometrika, 1975
An approach for multiple factor analysis of dichotomized variables is presented based on distribution of first and second order joint probabilities of binary scored items. The estimator is based on the generalized least squares principle. Standard errors and a test of the fit of the model is given. (Author/RC)
