Structuration d’un peuplement hétérogène au moyen d’éclaircies locales

Local rules optimization in a mixed stand. We present a treemarking model based on local rules, which optimizes the structure of the stand. The stand is divided into plots with constant number of trees. A plot is described by the number of trees in diameter classes for each species. These variables are random variables and their probability law are modeled by a mixture of multinomial distributi...

The authors of this handsomely produced volume describe Brodel's life in great detail on the basis of a large number of family letters. It is in fact more of a person...

Traitement Des Donnees Manquantes Au Moyen De L'Algorithme De Kohonen

Le traitement des données avec observations manquantes est un problème concret et toujours embarrassant lorsqu’il s’agit de données réelles. En effet dans les applications, on est très souvent en présence d’observations pour lesquelles on ne dispose pas de l’ensemble des valeurs des variables descriptives, et ceci se produit pour de nombreuses raisons : erreurs de saisie, rubriques non renseign...
