LISREL (linear structural relations) is a proprietary statistical software package used in structural equation modeling (SEM) for manifest and latent variables. It requires a "fairly high level of statistical sophistication".[1]
LISREL was developed in the 1970s by Karl Jöreskog, then a scientist at Educational Testing ServiceinPrinceton, New Jersey,[2] and Dag Sörbom, later both professors of Uppsala UniversityinSweden.[3] The most current version is LISREL 11 and can be downloaded from https://ssicentral.com/index.php/products/lisrel/.[4]
LISREL is mainly syntax-based, although recent versions have featured a graphical user interface (GUI).
SSI (Scientific Software International) has recently changed from e-Academy to a "home-built" solution for distributing the rental (6- or 12-month) versions of their software.
