Central limit theorems for Gaussian polytopes

Open access

Abstract

Choose n random, independent points in Rd according to the standard normal distribution. Their convex hull Kn is the Gaussian random polytope. We prove that the volume and the number of faces of Kn satisfy the central limit theorem, settling a well-known conjecture in the field.

  • Due to the central limit theorem, the ICA estimates can be obtained by determining the directions for which the nongaussianity is maximum.

    “Due to the well known central limit theorem (Barany, 2007), the ICA estimates can be obtained from the determination of the directions for which the nongaussianity is maximum.”

    From Passive Sonar Signal Detection and Classification Based on Independent Component Analysis (2011) · cites this paper as Barany, 2007

    The Abstract reports central limit theorems for the volume and number of faces of Gaussian random polytopes. Section 4 describes the general tendency of normalized sums toward a Gaussian distribution, but neither passage addresses ICA estimates or maximizing nongaussianity over directions. Searches for ICA and for projection directions found no passage supporting that inference. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
