Count responses: Poisson regression for contingency tables, loglinear

See http://www.chrisbilder.com/categorical for my book and http://www.chrisbilder.com/stat875 for my course notes. This section discusses count responses. The video was created for STAT 875 at the University of Nebraska-Lincoln. The purpose of the course is to provide an introduction to categorical data analysis for statistics and non-statistics graduate students.
