EQS - Structural Equation Modelling Software

EQS provides researchers and statisticians with a simple method for conducting the full range of structural equations models, including multiple regression, multivariate regression, confirmatory factor analysis, structured means analysis, path analysis, and multiple population comparisons. With EQS, no knowledge of matrix algebra is required.

EQS provides the most accurate known statistics for analysis on data that may not be multivariate normally distributed (real data are typically non-normal) with the Satorra-Bentler scaled chi-square, robust standard errors, and the Yuan-Bentler distribution-free statistics. EQS now includes polyserial and polychoric correlations for treating categorical data, additional exploration functions, enhancements to the RETEST and WTEST options, and the ability to import weight matrices.
