Abstract:
|
Transportation-related fatality risk is a function of many interacting human, vehicle, and environmental factors. Statistically valid analysis of such data is challenged both by the complexity of plausible structural models relating fatality rates to explanatory variables and by uncertainty about the probability distribution of the data. But, fortunately, generalized linear modeling and maximum quasi-likelihood estimation together provide an extraordinarily effective set of statistical tools for the analysis of such data. The goal of this talk is to illustrate and promote application of these tools to fatality risk analysis.
