Bertin-Plots and local models

Günther Sawitzki

Local models are models restricted in the scope of cases or variables or both. They occur naturally in the modelling process using Bertin graphs [de Falguerolles et al., 1997] and are the building blocks in tree based procedures such as CART and DART [Friedman, 1996].

We illustrate the definition and use of local models in the context of Bertin graphs, and their relation to the strategies layed out in [de Falguerolles et al., 1997].
