Soft Methodology and Random Information Systems
The zonoid trimmed regions induce the zonoid depth function that assigns to
each x € Rd the value ZD(x; F) := sup{a e (0, 1] : z € ZDa(F)}. The depth of a point
measures its centrality with respect to a probability distribution. For the zonoid
depth ...

Papers in Algebra, Analysis, and Statistics
It is clear from the definition that the sum of /c-zonoids is a k-zonoid and that the
affine image of a fe-zonoid is a fe-zonoid. o Every compact convex set in IR with a
centre of symmetry is a 1-zonoid (see for example [3]). It is also known that every
...
The measure μ of the previous theorem is called the generating measure of the
zonoid K. It is essentially unique, by Theorem C.2.1. Theorem 4.1.11. A projection
body is a centered zonoid. Conversely, every centered n-dimensional zonoid in ...

El We collect some consequences of these and former observations. Corollary
3.5.7 Every support set of a generalized zonoid is itself a generalized zonoid and
is, in particular, centrally symmetric. Every support set of a zonoid is a summand ...

Advances in Theoretical and Applied Statistics
By resorting both to multiple linear regression model and Lorenz zonoid tools,
one obtains LZ(Y) 20.245, LZ(YYJgO-Om, LzdkQgonos and LZ(ikhX-J'gO-054.
Through (Q) and (Q), the following single partial dependence measures can be ...

Stochastic and Integral Geometry
We put ΠX := Πd−1(γQ) and call Π X the associated zonoid of the hyperplane
process X. By (4.58), we have h(ΠX,u) = γ2 ∫ Sd−1 |〈u,v〉|φ(dv), u∈Rd, (4.59)
where φ is the spherical directional distribution of X. According to Theorem 14.3.4
, ...

Definition 1.14 (Zonoid and lift zonoid of a random vector). Let ξ be a random
vector in Rd. Its zonoid, Zξ, is the selection expectation of X = {0,ξ}. The lift zonoid,
̃Zξ, of ξ is the selection expectation of the segment in Rd+1 with the endpoints ...
