The aim of this paper is to prove a trace theorem for Besov functions in the metric setting, generalizing a known result from A. Jonsson and H. Wallin in the Euclidean case. We show that the trace of ...

Consider the regression y=f(x̃)+ε , where E(ε|x̃)=0 and the exact functional form of f is unknown, although we do know that f is homogeneous of known degree r. Using a local linear approach, we ...
