Description Usage Arguments Details Author(s) Examples
Computes the Projection depth of a point or vectors of points with respect to a multivariate data set.
1 | depthProjection(u, X, ndir = 1000, threads = -1)
|
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). |
ndir |
number of directions used in computations |
threads |
number of threads used in parallel computations. Default value -1 means that all possible cores will be used. |
Irrespective of dimension, Projection and Tukey's depth is obtained by approximate calculation.
Returns the depth of multivariate point u
with respect to data set X
