Other depths include the zonoid depth or [L.sub.1] depth among many others.
This method was used, for example, by Mosler and Hoberg  who combined zonoid and Mahalanobis depth.

Extremum problems for the metric mean values will be discussed at the end of the paper by introducing an associated zonoid for STIT tessellations.
The centrally symmetric convex body [PI]([S.sub.v], R) is called Steiner compact associated with the law of the STIT tessellation or its associated zonoid, by referring to the characteristic property of [PI]([S.sub.v], R).
