Visualization of Interaction Effects in Multiple Regression

Developers: Dr. Chong Ho Yu, Dr. John Behrens, Arthur, Natalie Schroeder-Soltis Software: Mathematica, Fusion Recorder, Adobe Premiere, Adobe After Effects, Media Cleaner Pro, Macromedia Director Description: Interaction effects in multiple regression are very abstract and complex. In this tutorial, a statistics learner can visualize high-dimensional regression models using animated QuickTime movies. The following movies illustrate how the relationship among three variables depend on the fourth variable. Caution: it takes a few seconds to load the tutorial through a T1 or E1 line, but it takes a long time to load it via a modem connection. An alternate version (Shockwave) was created for learners who prefer viewing graphics frame by frame to time-based movies.
