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:

    Glue Logo

    Glue is a Python framework to link visualizations of multiple related datasets. Its goal is to let users easily inter-compare data across several files. 

    Advanced Video Processing

    Digital video editing and computer graphics have allowed unbridled creativity for professional film makers. However, the software tools and techniques used to accomplish these tasks require expert knowledge and are often slow. With this project, we aim to improve existing video processing tools which currently slow down existing users and block new users from the creative process.

    The Connectome Project

    Colorful dotsWe are interested in the segmentation, visualization and analysis of brain scans in electron and optical microscopy in the multi-terabyte range.

    Sponsored by NSF, NIH and private foundations.

    Flip flopReal-world objects have a characteristic shape, appearance and response to physical interactions. Computer graphics was concerned with modeling those three components of an object to bring more realism onto our computer display. In addition, CAD (computer-aided design) tools and techniques to edit and create geometry were developed to accurately and intuitively design the shape of objects. This shapes can then directly be fabricated.

    Biomedical Visualization

    Artery blue greenWe are working to apply novel visualization tools and techniques to leading edge biomedical research. Our current focus is collaborating with the Multiscale Hemodynamics Project which is a collaboration of doctors, physicists, and computational scientists working together to model human blood flow through the coronary arteries.

    FITS Releases

    The File Information Tool Set (FITS) identifies, validates, and extracts technical metadata for various file formats. It wraps several third-party open source tools, normalizes and consolidates their output, and reports any errors. FITS was created by the Harvard Library for use in its Digital Repository Service (DRS) but was released as open source in 2009.
