What are the differences between Amos and EQS?
Another comparison we are often asked to make is the one between Amos and the EQS program (by Peter Bentler). Several aspects from the Amos-vs.-LISREL discussion (above) apply to EQS as well, so the comparison with EQS can be kept short. Most structural equation models can be set up and estimated with either Amos or EQS — which program to use is often a matter of price, support and personal preference. Apparently the difference between Amos and EQS is not terribly great. EQS has somewhat of a niche in methods for elliptical distribution methods, robustified chi-square tests, and integrated exploratory data analysis modules. On the other hand, Amos features full-information ML model estimation with incomplete (or missing) data, and has a variety of sophisticated bootstrap simulation tools for analyzing non-normal data.
