frechetMedian: Calculate the Fréchet median

In manifold: Operations for Riemannian Manifolds

Calculate the Fréchet median

Description

Calculate the Fréchet median

Usage

frechetMedian(mfd, X, ...)

## Default S3 method:
frechetMedian(
  mfd,
  X,
  mu0,
  weight = NULL,
  tol = 1e-09,
  maxit = 1000,
  alpha = 1,
  ...
)

Arguments

mfd	A manifold object created by createM
X	A matrix with each column being a point on the manifold.
...	Passed into specific methods
mu0	A matrix of starting points. Each column corresponds to a starting point. If there are multiple columns, then a multistart algorithm is used.
weight	A vector of weights for the observations
tol	The threshold for determining convergence
maxit	Maximum iteration
alpha	The step size parameter. See Fletcher et al. (2008) CVPR

Value

A matrix with 1 column containing the Fréchet median
