Dear R users, Version 3.0-0 of the sem package is now on CRAN. From the package NEWS file:
o Compiled code for optimization. o Added multi-group models. o Modification indices for equality-constrained parameters. o weights argument added to tsls(). o raw argument added to cfa(). Of these changes, the first two are the most significant, and the first -- the use of compiled code to improve performance substantially -- was implemented by Zhengua Nie, who has joined me and Jarrett Byrnes as a co-developer of the package.
