Abstract: In statistical studies, generalized linear models (GLMs) are usually preferred for
modeling incidence rates, often with extensions to zero-inflated GLMs when the proportion of zero counts is large. However Warton has shown that for many ecological studies, simple linear models fitted to log-transformed counts do surprisingly well. In this study, we used data comprising a sizable set of pneumonia incidence rates. We compared the negative binomial GLM with a log transformed linear model, and found further support for this simpler alternative method. |
