An alternative procedure for estimating structural
equations models is described. The two-stage procedure,
Path Analysis of Covariance Matrix (PACM), separately
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 advantages
when dealing with large-scale problems, model
misspecifications, collinearity among indicators, and
missing data. Index terms: causal models, confirmatory
factor analysis, LISREL, path analysis, structural
