Website for CATEGORICAL DATA ANALYSIS, 3rd edition

Here are datasets for many of the main examples in the text, and for some of the exercises. The separate directory data files. contains some individual files (Crabs for Table 4.3, Teratology for Table 4.7, Credit for Exercise 5.22, Endometrial for Table 7.2, Infection for Table 6.9, SoreThroat for Table 6.15, Substance use for Table 9.3, MBTI for Table 9.17, Substance2 for Table 10.1, Insomnia for Table 12.3, Abortion for Table 13.3). The horseshoe crab data are used to illustrate logistic regression (modeling whether a female crab has at least one satellite) and models for count data (e.g., negative binomial modeling of the number of satellites). For the count data, better models allow zero-inflation. See crab zero-inflation for an excerpt about this, taken from my new book "Foundations of Linear and Generalized Linear Models" (published by Wiley, 2015).
