For those who purchased, or otherwise obtained, my text, Negative Binomial
Regression (2007, Cambridge University Press), I have written a 21 page
addendum that provides more specifics concerning the meaning and interpretation of
risk and risk ratio than is currently discussed in the text. In addition, I
provide details about constructing and interpreting several types of
interaction terms for count models; e.g., Binary X Binary, Binary X Continuous, and
Categorical X Continuous. These seem to me to be the most common types of
interactions used in research. The addendum is intended to be a summary-type guide
for understanding these specific topics, and should be thought of as an
extension to the discussion presented in the text.
The addendum can be downloaded at _www.statistics.com/hilbe_
(http://www.statistics.com/hilbe) . I wrote it initially for my current statistics.com course
on Modeling Count Data, but thought that it should be made available to
anyone who has the text.
