a n x d matrix of d dimensional data vectors.

data

This function returns the value of the statistic of the test of multivariate normality (also called energy test) as in Sz&lt;U+00E9&gt;kely and Rizzo (2005). Note that the scaled residuals use another scaling in the estimator of the covariance matrix as the other functions of the package <code>mnt</code>!
It is equivalent to the function <code><a rd-options="energy:mvnorm.test" href="/link/mvnorm.e?package=mnt&version=1.3&to=energy%3Amvnorm.test" data-mini-rdoc="energy:mvnorm.test::mvnorm.e">mvnorm.e</a></code>.

Various affine invariant multivariate normality tests are provided. It is designed to accompany the survey article Ebner, B. and Henze, N. (2020) <arXiv:2004.07332> titled "Tests for multivariate normality -- a critical review with emphasis on weighted L^2-statistics". We implement new and time honoured L^2-type tests of multivariate normality, such as the Baringhaus-Henze-Epps-Pulley (BHEP) test, the Henze-Zirkler test, the test of Henze-Jim<c3><a9>nes-Gamero, the test of Henze-Jim<c3><a9>nes-Gamero-Meintanis, the test of Henze-Visage, the D<c3><b6>rr-Ebner-Henze test based on harmonic oscillator and the D<c3><b6>rr-Ebner-Henze test based on a double estimation in a PDE. Secondly, we include the measures of multivariate skewness and kurtosis by Mardia, Koziol, Malkovich and Afifi and M<c3><b3>ri, Rohatgi and Sz<c3><a9>kely, as well as the associated tests. Thirdly, we include the tests of multivariate normality by Cox and Small, the 'energy' test of Sz<c3><a9>kely and Rizzo, the tests based on spherical harmonics by Manzotti and Quiroz and the test of Pudelko. All the functions and tests need the data to be a n x d matrix where n is the samplesize (number of rows) and d is the dimension (number of columns).

SR function

This function returns the value of the statistic of the test of multivariate normality (also called energy test) as in Sz&lt;U+00E9&gt;kely and Rizzo (2005). Note that the scaled residuals use another scaling in the estimator of the covariance matrix as the other functions of the package <code>mnt</code>!
It is equivalent to the function <code><a rd-options='energy:mvnorm.test' href='mvnorm.e'>mvnorm.e</a></code>.
