Abstract

. We consider estimation of the upper boundary point F−1 (1) of a distribution function F with finite upper boundary or ‘frontier’ in deconvolution problems, primarily focusing on deconvolution models where the noise density is decreasing on the positive halfline. Our estimates are based on the (non‐parametric) maximum likelihood estimator (MLE) of F. We show that (1) is asymptotically never too small. If the convolution kernel has bounded support the estimator (1) can generally be expected to be consistent. In this case, we establish a relation between the extreme value index of F and the rate of convergence of (1) to the upper support point for the ‘boxcar’ deconvolution model. If the convolution density has unbounded support, (1) can be expected to overestimate the upper support point. We define consistent estimators , for appropriately chosen vanishing sequences (βn) and study these in a particular case.
