Adaptive minimax testing in the discrete regression scheme

Abstract: We consider the problem of testing hypotheses on the regression function from n observations on the regular grid on [0, 1]. We wish to test the null hypothesis that the regression function belongs to a given functional class (parametric or even nonparametric) against a composite nonparametric alternative. The functions under the alternative are separated in the L 2 -norm from any function in the null hypothesis. We assume that the regression function belongs to a wide range of Hölder classes but as the smoothn… Show more

“…As for the fixed design regression model, Härdle and Kneip in [9] state a first minimax result over some particular Sobolev classes. Gayraud and Pouet in [7] consider the more general problem of testing composite null hypotheses such as "f belongs to some parametric family". They give the minimax rates of testing for this problem with respect to the L 2 −norm over some Hölder classes and prove that these rates are of the same order as those obtained for simple hypotheses in the Gaussian white noise model (see [12]).…”

“…Some functional estimation problems, whose goal is to infer f (θ) for a given function f , are also related to some composite-composite testing problems. In fact, some work on functional problems [7,8,10,19,32] and adaptive confidence regions (e.g. [9,11,23,37]) have lead to progress in the understanding of such testing problems.…”
