Multivariate Intensity Estimation via Hyperbolic Wavelet Selection
Nathalie Akakpo
We propose a new statistical procedure able in some way to overcome the curse of dimensionality without structural assumptions on the function to estimate. It relies on a least-squ…
Testing monotonicity via local least concave majorants
Nathalie Akakpo, Fadoua Balabdaoui, Cécile Durot
We propose a new testing procedure for detecting localized departures from monotonicity of a signal embedded in white noise. In fact, we perform simultaneously several tests that a…
Adaptation to anisotropy and inhomogeneity via dyadic piecewise polynomial selection
Nathalie Akakpo
This article is devoted to nonlinear approximation and estimation via piecewise polynomials built on partitions into dyadic rectangles. The approximation rate is studied over possi…
Detecting change-points in a discrete distribution via model selection
Nathalie Akakpo
This paper is concerned with the detection of multiple change-points in the joint distribution of independent categorical variables. The procedures introduced rely on model selecti…
