Multivariate tests of location of one or more samples based on spatial signs and (signed) ranks. In case of one sample the null hypothesis about a given location is tested. In case of several samples the null hypothesis is that all samples have the same location.
Spatial location
(Package: SpatialNP) :
Multivariate location estimates based on spatial signs and signed ranks
Iterative algorithms to find spatial median, multivariate Hodges-Lehmann estimate of location, their affine equivariant versions and k-step versions of these.
This package contains tests and an estimate of location, tests of independence, tests of sphericity and several estimates of shape all based on spatial signs, symmetrized signs (that is, signs of pairwise differences), ranks and signed ranks.
Test of independence between two sets of variables. Inference is based on the spatial signs of the observations, symmetrized signs of the observations or spatial signed ranks of the observations.
