Abstract

In this paper, we study the maximum likelihood estimator (MLE) of the parameter vector of a discrete multivariate crash frequencies model used in the statistical analysis of the effectiveness of a road safety measure. We derive the closed-form expression of the MLE afterwards we prove its strong consistency and we obtain the exact variance of the components of the MLE except one component whose variance is approximated via the delta method.

Dans cet article, nous étudions l'estimateur du maximum de vraisemblance (EMV) du vecteur de paramètres d'un modèle discret multivarié utilisé dans l'analyse statistique de l'efficacité d'une mesure de sécurité routière. Nous obtenons l'expression analytique exacte de l'EMV après quoi nous prouvons sa forte consistance et nous obtenons la variance exacte des composantes de l'EMV, sauf pour une composante dont la variance est approximée par la méthode delta.
