Amos(tm) 5.0 enables researchers to leverage structural equation modeling (SEM) to explore and confirm complex relationships Latest version of modeling software establishes industry benchmark for SEM, extends capabilities for social science, public health and market research communities

CHICAGO, June 26, 2003 - SPSS Inc. (Nasdaq: SPSS), the leading provider of predictive analytics, today announced the immediate availability of Amos(tm) 5.0, the powerful structural equation modeling software package developed by Amos Development Corp. Using Amos, researchers can propose complex theories of how and why variables might affect each other, and then verify whether the data supports their proposed models. For example, market researchers can use Amos to improve their marketing strategy by modeling the impact of customer satisfaction on brand loyalty.

Structural equation modeling (SEM) is a holistic approach to modeling complex dependencies among unobserved or hypothetical variables, such as perceptions, beliefs and attitudes. With SEM, any variable can serve as a predictor of any other variable, whether it is observed or hypothesized. By simultaneously evaluating dependencies among variables, SEM extends traditional modeling techniques by providing additional insight into the underlying nature of relationships.
