Shape constrained estimators in inverse regression models with convolution-type operator
Birke, Melanie; Bissantz, Nicolai - 2007
In this paper we are concerned with shape restricted estimation in inverse regression problems with convolution-type operator. We use increasing rearrangements to compute increasingand convex estimates from an (in principle arbitrary) unconstrained estimate of the unknown regression function. An...
