Universal pointwise selection rule in multivariate function estimation
Alexander Goldenshluger, Oleg Lepski
In this paper, we study the problem of pointwise estimation of a multivariate function. We develop a general pointwise estimation procedure that is based on selection of estimators…
Asymptotic data analysis on manifolds
Harrie Hendriks, Zinoviy Landsman
Given an m-dimensional compact submanifold of Euclidean space , the concept of mean location of a distribution, related to mean or expected vector, is ge…
A universal procedure for aggregating estimators
Alexander Goldenshluger
In this paper we study the aggregation problem that can be formulated as follows. Assume that we have a family of estimators built on the basis of available observati…
Recovering convex boundaries from blurred and noisy observations
Alexander Goldenshluger, Assaf Zeevi
We consider the problem of estimating convex boundaries from blurred and noisy observations. In our model, the convolution of an intensity function is observed with additive Ga…
