18. On an estimator achieving the adaptive rate in nonparametric regression under ${L}^{p}$-loss for all $1\le p\le \mathrm{\infty }$. preprint
This is an update of the working paper pdf. In the first version, we only consider simultaneous adaptation with respect to ${L}^{2}$- and ${L}^{\mathrm{\infty }}$-loss. This article might be easier to read and includes a small numerical study.
19. Multiscale methods for shape constraints in deconvolution: Confidence statements for qualitative features.pdf supplement
Annals of Statistics, Volume 41, Number 3, 1299-1328, 2013. With Axel Munk and Lutz Dümbgen.
A first draft of this paper appeared under the title: "Multiscale methods for shape constraints in deconvolution" in 2011. pdf. It contains essentially the same results, but under a very strong assumption on the decay of the Fourier transform of the error density. The first version is much easier to read and does not require the theory of pseudo-differential operators.
