What can we Learn from the Path Equations?: Identifiability, Constraints, Equivalence
Roderick P. McDonald · Psychometrika · 2002
Procedures are given for determining identified parameters, finding constraints on the covariances, and checking equivalence, in acyclic (recursive) linear path models with correlated error terms (disturbances), by inspection of the path equations, aided by simple recursions. This provides a useful and general alternative to the employment of directed acyclic graph theory for such purposes.
