LISREL


LISREL is a proprietary statistical software package used in structural equation modeling for manifest and latent variables. It requires a "fairly high level of statistical sophistication".

History

LISREL was developed in the 1970s by Karl Jöreskog, then a scientist at Educational Testing Service in Princeton, New Jersey, and Dag Sörbom, later both professors of Uppsala University in Sweden. The most current version is LISREL 10.1.

Command language, graphical user interface and delivery

LISREL is mainly syntax-based, although recent versions have featured a graphical user interface.
SSI has recently changed from e-Academy to a "home-built" solution for distributing the rental versions of their software.
