Abstract: | In this paper we consider models involving the convex hull operation of the parameter and the noise i.e. Yi = CH(A, XX). Then we generalize the basic models to ANOVA models; i.e. Yij=CH(A∪Bj,Xij). In some cases the consistent estimators for the J U new parameters are derived. Assuming the existence of density forrandom convex sets, we derive the likelihood for the convex hull model. We then find the maximum Likelihood Estimators for the parameters. Examples for some random convex sets with finite dimensional distributions are derived to show how good these estimators are. |
