This paper deals with measuring the influence of observations on the results obtained with CART classification trees. To define the influence of individuals on the analysis, we use influence functions to propose some general criterions to measure the sensitivity of the CART analysis and its robustness.

In addition, the analysis is extended to the pruned sequences of CART… CONTINUE READING
