Wrapper for Joint Affine Equivariant Estimation of Multivariate Median and Tyler's Shape Matrix

Description

The function returns, for some multivariate data, the joint affine equivariant estimation of multivariate median and Tyler's shape matrix obtained from HR.Mest.

Usage

HRMEST(x, ...)

Arguments

x	numeric data matrix or dataframe.
...	further arguments passed on to HR.Mest.

Details

The use of the ICSShiny function requires to pass as an argument a list with: the location vector and the scatter matrix, as the first two arguments.

The HRMEST function is mainly for internal use in the ICSShiny application.

Value

location	the location vector obtained from the joint affine equivariant estimation of multivariate median and Tyler's shape matrix.
scatter	the scatter matrix obtained from the joint affine equivariant estimation of multivariate median and Tyler's shape matrix.
