Empirical Bayes approach to the estimation of "unsafety": the multivariate regression method by Hauer, E

“…There are two kinds of clues to the unsafety of an entity: its traits (such as traffic, geometry, age, or gender) and its historical accident record. The…”

Overdispersion in modelling accidents on road sections and in Empirical Bayes estimation by Hauer, Ezra

“…In multivariate statistical models of road safety one usually finds that the accident counts are ‘overdispersed’. The extent of the overdispersion is itself…”
