Computing the Oja Median in R: The Package OjaNP
Subject
Oja median, Oja signs, Oja signed ranks, Oja ranks, R, C++.
Description
The Oja median is one of several extensions of the univariate median to the multivariate case. It has many desirable properties, but is computationally demanding. In this
paper, we first review the properties of the Oja median and compare it to other multivariate medians. Then, we discuss four algorithms to compute the Oja median, which
are implemented in our R package OjaNP. Besides these algorithms, the package contains
also functions to compute Oja signs, Oja signed ranks, Oja ranks, and the related scatter concepts. To illustrate their use, the corresponding multivariate one- and C-sample
location tests are implemented.
