Two-Step Weighted Least Squares Factor Analysis of Dichotomized Variables
Christoffersson, Anders
Psychometrika, 42, 3, 433-8, Sep 77
A two-step weighted least squares estimator for multiple factor analysis of dichotomized variables is discussed. The estimator is based on the first and second order joint probabilities. Asymptotic standard errors and a model test are obtained by applying the Jackknife procedure. (Author)
