Shape restrictions
WebbNonparametric inference under shape restrictions is often computationally demanding. For instance, inference based on test inversion would require agrid search over a high-dimensional sieve parameter space. In this paper, we propose a computationally attractive method for nonparametric inference about regression functions under shape restrictions. WebbThis paper deals with a nonparametric shape respecting estimation method for U-shaped or unimodal functions. A general upper bound for the nonasymptotic $\\mathbb{L}_{1}$-risk of the estimator is given. The method is applied to the shape respecting estimation of several classical functions, among them typical intensity functions encountered in the …

Webb1 nov. 2015 · This paper uses shape restrictions, such as monotonicity or convexity, to achieve interval identification of L (g). The paper shows that under shape restrictions, L (g) is contained in an interval whose bounds can be obtained by solving linear programming problems. Inference about L (g) can be carried out by using the bootstrap. Webbshape restrictions and their effect upon efficiency bounds. The results in this paper should be of particular interest to practitioners in the field, because they provide some new insights into incorporating shape restrictions in estimation procedures. The paper is organized as follows. Section 2 lists the maintained assump-tions.
