LP Depth

Description

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

Usage

depthLP(u, X, pdim = 2, la = 1, lb = 1, threads = -1, func = NULL)

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).

pdim

dimension used in calculating depth function.

la

slope the weighing function.

lb

intercept in the weighing function.

threads

number of threads used in parallel computations. Default value -1 means that all possible cores will be used.

func

the weighing function. Currently it is not supported.

Details

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