Structural Equation Models (sem)



sem is an R package for fitting structural-equation models. The package supports general structural equation models with latent varibles, fit by maximum likelihood assuming multinormality, and single-equation estimation for observed-variable models by two-stage least.squares.

The sem package is available on the Comprehensive R Achive Network (CRAN).

For more information (though slightly out-of-date), see J. Fox (2006), "Structural Equation Modeling With the sem Package in R." Structural Equation Modeling, 13:465-486.
