CEM for SPSS

    Authors:  Matthew Blackwell, Stefano Iacus, Gary King, and Giuseppe Porro

    This program is designed to improve the estimation of causal effects via an extremely powerful method of matching that is widely applicable and exceptionally easy to understand and use (if you understand how to draw a histogram, you will understand this method). The program implements the Coarsened Exact Matching (CEM) algorithm described in:

    How To Apply


    Undergraduates interested in participating in the Research Scholars Program should check Current Opportunities to find out more about projects currently in need of researchers.  To apply, send a resume and cover letter detailing relevant qualifications and experience to the contact person listed under the project description. 


    ZeligChoice adds several choice regressions - ordinal, multinomial and bivariate - to Zelig.


    ZeligGAM adds general additive models to Zelig.


    This package adds multilevel (a.k.a. hierarchical or mixed-effect) models to Zelig.


    ZeligNetwork adds social-network regressions to Zelig.


    Zelig is a single, easy-to-use program that can estimate, help interpret, and present the results of a large range of statistical methods. It literally is "everyone's statistical software" because Zelig uses (R) code from many researchers. We also hope it will become "everyone's statistical software" for applications, and we have designed it so that anyone can use it or add their methods to it.

    OpenMIMS Data Analysis Software

    OpenMIMS is an ImageJ plugin. It can run on any system running ImageJ.

    ImageJ Installation:

    • Download (contains jar files, documentation and source code).
    • Extract the contents to the ImageJ 'plugins' folder. **NOTE: Overwrite any previous versions of the jar files contained in the zip file that may already exist in the 'plugins' folder.
    • Restart ImageJ.

    Fiji Installation


    • ImageJ 1.43u (or higher).
    • Java 1.6 (or higher).


    Test Data:

    • SampleData1 (4 masses, single plane, 2.1Mb) im
    • SampleData2 (90M) zip

    After installing, launch ImageJ and under the Plugins menu, select the Open MIMS Image. This will open the plugin. Files can then be opened either using File>Open MIMS Image or by dragging and dropping a file over the graphical interface.

    If you are having issues opening images try opening the sample data file. If you are unable to open the sample than the problem most likely resides in the installation process. Make sure to overwrite/delete all previous versions of any .jar files that may exist in your 'plugins' directory. If you are able to open sample data but not your own images, please contact us with any error report that may have been generated at the following email address:


    Access the Read-only SVN Source Code Repository

    To check out a local copy of the OpenMIMS repository, use the following command:

                > svn checkout

    Access the Source Code through NetBeans

    Alternatively, users may perform a check-out of the OpenMIMS project from within the Netbeans IDE by clicking the


    menu item and entering the following web address into the Repository field:

    NetBeans screen 1
    Click Next and fill in the appropriate fields for your system:
    NetBeans screen 2
    Click Finish. At this point you should be able to run the project and the OpenMIMS GUI should appear. You can test the plugin using the test data provided above.
