1. Acknowledging the fact that the language R is now the most obvious path forward in quantitative analysis, I am now including tutorials using the R package Lavaan. If you are unfamiliar with the R project, I suggest you search it out. A book search at Amazon.com will show that there are new books on detailed applications in R popping out like popcorn!

2. I am currently in the process of developing an implementation of next-generation SEM (working with others). This next generation will abandon the matrix-based approach of analyzing covariances, which has served us so very well this past 40 years, for a graphical modeling approach that relies on local estimation and permits many enhancements. As that implementation takes shape, a new top tab will be added to describe this exciting development.
