The latest java plug in (Java 7u51) creates a problem for GeSCA.

One way to solve it is to make an exception rule for our server ( 
•If you are using a Windows operating system, click on Start Button, then choose Control Panel.

•Enter "Java" in the search text area on the top right of the window that appears. This will get you to the Java Control Panel.

•If you are using a Mac operating system, click on the apple icon, choose "system preferences" and 
click on the "Java" icon to get to the Java Control Panel.*a helpful link for Mac users*

•Once you have opened the Java Control Panel, click on the 'Security' tab.
•Click on the 'Edit Site List', then click on the 'Add' Button and type in the following text. 
Click "OK" and restart your computer. Then GeSCA should work.

In some instances, the 'Edit Site List' button will not be visible.
This often occurs when more than one version of the Java plug-in is installed on your computer (including the latest one - java7u51). In that case, it is necessary to uninstall all the old versions of java except the latest one (java7u51). Then the 'Edit Site List' button should become visible. 

Thanks for using GeSCA !


A user’s manual is available here that demonstrates how to use GeSCA.

(Many thanks to Professor Richard Bagozzi for kindly permitting us to use this dataset)

  • A sample dataset can be downloaded here as a .xls file.
  • A sample model file can be downloaded here.

Notice :

* Note that if Google Chrome does not allow Java to run, please use MS Internet Explorer.
* Attention: Please follow these instructions to run the program with recent Java versions.
1. When users enter GeSCA, they may see a Java popup window asking “Block potentially unsafe components from being run?”,  please choose “No” to run the software.

2. Important update (November 3, 2010): We fixed a bug regarding inconsistency in scaling observed and latent variables. In the previous version, observed variables were standardized while latent variables normalized. We now normalize both observed and latent variables. This bug was unlikely to affect parameter estimates substantially in most cases, whereas it might result in less accurate FIT and AFIT values. We thank Dr. Jörg Henseler for his personal inquiries and comments that greatly facilitated detecting the scaling inconsistency.

3. Mac users can run GeSCA in both Firefox and Safari. However, when they run GeSCA in Safari, they will see the screen flicker every second. This does not affect the result of analysis.

4. Users must have Java installed to run GeSCA. If Java is not installed, a small red X will appear on the screen. You can download Java here.

5. Internet Explorer is required to execute the application.
