Hi R-colleagues. I have been using the sem(sem) function. It uses maximum likelyhood as optimizing. method. According to simulation study in UmeƄ Sweden (http://www.stat.umu.se/kursweb/vt07/stad04mom3/?download=UlfHolmberg.pdf Sorry it is in swedish, except the abstract) maximum likelihood is OK for large samples and normal distribution the SEM-problem should be optimized by GLS (Generalized Least Squares).
So to the question: Is there any R-function that solves SEM with GLS?
