Developed by one of the world's leading authorities on the subject, Dr. Peter M. Bentler, 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. Users agree that EQS is more complete and much easier to use than other products such as LISREL. 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. These features are not available in other modeling programs.
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.
