PAC M : A Two-Stage Procedure for Analyzing Structural ModelsColumbia University
University of California, Los Angeles An alternative procedure for estimating structural equations models is described. The two-stage proce dure, Path Analysis of Covariance Matrix (PACM), sep arately estimates the measurement and structural models using standard least-squares procedures. PACM was empirically compared to simultaneous maximum likelihood estimation of measurement and structural models using LISREL. PACM produced results similar to LISREL in many cases; it also seems to have advan tages when dealing with large-scale problems, model misspecifications, collinearity among indicators, and missing data.
Key Words: Index terms: causal models confirma tory factor analysis LISREL path analysis structural equations models.
