A Program for Standard Errors of Indirect Effects in Recursive Causal Models.
Wolfle, Lee M.; Ethington, Corinna A.
In his early exposition of path analysis, Duncan (1966) noted that the method "provides a calculus for indirect effects." Despite the interest in indirect causal effects, most users treat them as if they are population parameters and do not test whether they are statistically significant. Sobel (1982) has recently derived the asymptotic distribution of indirect effects. His algorithm involves calculating partial derivatives of indirect effects with respect to structural parameters, which if done by hand is tedious and subject to computational errors. This paper describes a new FORTRAN computer program that provides the causal modeler with standard errors of indirect effects for recursive causal models. The only input data required is a matrix of structural parameter estimates along with their variances and covariances. (Author)
