Algorithms and Estimation for graph data

Participants: R. Azais, F. Bouguet, T. Bastogne

Tree-structured data naturally appear in various fields, particularly in biology where plants and blood vessels may be described by trees. The paper [27] is devoted to the estimation of the relative scale of ordered trees that share the same layout. The theoretical study is achieved for the stochastic model of conditioned Galton-Watson trees. New estimators are introduced and their consistency is stated. A comparison is made with an existing approach of the literature. A simulation study shows the good behavior of our procedure on finite-sample sizes.
