Two-step weighted least squares factor analysis of dichotomized variables
Psychometrika（1977）
摘要
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.
