• EQS STRUCTURAL EQUATION MODELINE SOFTWARE
• ?
• Developed by one of the world's leading authorities on the subject, Dr. Pentler, EQS provides researchers and statisticians with a simple method for conducting the full range of structural equations models including multiple, multivariate regression, confirmatory factor analysis, structured means analysis, path analysis, and multiple population. 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 reguired！
• ?
• EQS handles a wide variety of structural equation models in all types of computer environments. Users can draw a path diagram using EQS' drawing tool to create their model, and use the most advanced statistics to correctly treat non-normal data.
• ?
• EQS provides the most accurate known statistics for analysis on data that may not be multivariate normally distributed 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. Already known for combining technical sophistication with ease of use, EQS makes structural equations modeling even easier with Diagrammer, EQS' new model drawing tool!
• ?
• Make just a few clicks on the mouse and you can draw presentation-quality diagrams. Once your model is drawn, choose Build EQS from the scroll-down menu and EQS runs your model, based on the diagram. When you are ready to present results, simply print the diagram directly or cut and paste into your favorite word processor for final production.
• Improved workflow with EQS Data preparation and eva luation that previously had to be done with other programs is now handled seamlessly and efficiently within EQS. Simply enter data directly into EQS' Spreadsheet Editor, import via standard formats (dBase, Lotus, etc.), or cut and paste data (raw data, correlation matrix, etc.) from another package. In the spreadsheet users can easily transform variables, edit data, or perform exploratory factor analysis to create an automatic model setup.
• ?
• Full range of modeling features
  EQS tests the full range of structural equations models including multiple regression, multivariate regression, confirmatory factor analysis, structured means analysis and multiple population comparisons.
  EQS also includes polyserial and polychoric correlations for treating categorical data, the Satorra-Bentler scaled chi-square statistic, enhancements to the RETEST and WTEST options, and the ability to import weight matrices.
• ?
• Extensive statistical and plotting options
  EQS combines statistical analysis capabilities (descriptive, t tests, ANOVA, multiple and stepwise regression, etc.) with data exploration plots (scatter plot, histogram, matrix plot, pie chart, multiple plot, etc.) to provide researchers with coordinated algebraic as well as graphical views of their data. Insights gained from these views will help users to efficiently formulate an optimal model. There is no need to switch between different software packages to perform various analyses, allowing users more time to focus on their model.
