The following is a list of software programs useful for path analysis, structural equations modelling (SEM) or exploration of causal structures. The inclusion of a program in this list is not an endorsement; I have not even used many of the listed programs. Since new versions of these programs are constantly being produced, you should visit the Internet websites before choosing.
