SEM software in the market today

• LISREL (one of the leaders in SEM and longtime advocate of SEM)
• IBM-SPSS AMOS (a bit expensive from IBM, but tech support is worth it)
• SMART PLS (freeware, uses partial least squares method and can run on a small sample size)

Most of these software are used by Statisticians who want to look deeper into their models by using moderation and mediation, Most of these are present in research journals and higher education.
