LISREL is the pioneering software for structural equation modeling, now including statistical methods for complex survey data. The LISREL model, methods and software have become synonymous with structural equation modeling (SEM).
SEM allows researchers in the social sciences, management sciences, behavioral sciences, biological sciences, educational sciences and other fields to empirically assess their theories. These theories are usually formulated as theoretical models for observed and latent (unobservable) variables. If data are collected for the observed variables of the theoretical model, the LISREL program can be used to fit the model to the data.
Fixes to all the bugs reported by end users of LISREL 9.1 for Windows. Structural Equation Modeling. If an LSF file is read in (single group case), then moment matrices are based on the definitions of the variables contained in the LSF file. For example, if all variables are declared.
