Abstract

For the first time, a statistical analysis of the number of deaths due to Boko Haram activities is provided. The analysis is based on some newly proposed discrete distributions. The distributions are fitted to the data using the method of maximum likelihood. The discrete Chen distribution is found to give the best fit. Its parameters are allowed to vary linearly with time to capture the variability in the number of deaths resulting from Boko Haram attacks. Predictions are given in terms of possible future number of deaths. As a byproduct, some basic properties of the discrete Chen distribution are provided.

Résumé

Pour la première fois, une analyse statistique du nombre de décès dus aux activités de Boko Haram est fournie. L'analyse est basée sur des distributions discrètes nouvellement proposées. Les distributions sont adaptées aux données en utilisant la méthode du maximum de vraisemblance. La distribution discrète de Chen est trouvée pour donner le meilleur ajustement. Ses paramètres sont autorisés à varier linéairement avec le temps pour capturer la variabilité dans le nombre de décès résultant des attaques de Boko Haram. Les prédictions sont données en termes de nombre futur possible de décès. En tant que sous-produit, certaines propriétés fondamentales de la distribution discrète de Chen sont fournies.
