Euclidean Depth

Description

Computes the euclidean depth of a point or vectors of points with respect to a multivariate data set.

Usage

depthEuclid(u, X)

Arguments

u

Numerical vector or matrix whose depth is to be calculated. Dimension has to be the same as that of the observations.

X

The data as a matrix, data frame or list. If it is a matrix or data frame, then each row is viewed as one multivariate observation. If it is a list, all components must be numerical vectors of equal length (coordinates of observations).

Details

Calculation of Euclidean depth is exact.

Returns the depth of multivariate point u with respect to data set X.
