Depth statistics
K Mosler - Robustness and complex data structures: Festschrift in …, 2013 - Springer
Abstract In 1975 John Tukey proposed a multivariate median which is the 'deepest'point in a
given data cloud in ℝ d. Later, in measuring the depth of an arbitrary point z with respect to …

Exact computation of the halfspace depth
R Dyckerhoff, P Mozharovskyi - Computational Statistics & Data Analysis, 2016 - Elsevier
For computing the exact value of the halfspace depth of a point wrt a data cloud of n points in
arbitrary dimension, a theoretical framework is suggested. Based on this framework a whole …

From depth to local depth: a focus on centrality
D Paindaveine, G Van Bever - Journal of the American Statistical …, 2013 - Taylor & Francis
Aiming at analyzing multimodal or nonconvexly supported distributions through data depth,
we introduce a local extension of depth. Our construction is obtained by conditioning the …
