Suppose I have a two-way table of nominal category (party affiliation) X ordinal category (political ideology):
party affiliation X (3 levels) - democratic, independent, and republic political ideology Y (3 levels) - liberal, moderate, and conservative The dependent variable is the frequency (or count) for all the two- way cells sampled from the voters. I want to test whether there is any party affiliation effect, and, if there is, the pair-wise contrasts. I have never used glm (I assume this the program I should use) before, so I am not so sure how I can code the two independent variables reflecting the fact that one is nominal while the other is ordinal and how to formulate the model. Any help is highly appreciated, Gang ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
