Find the kurtosis coefficient for multivariate data

Contributed by: Wolfram Research

ResourceFunction["MultivariateKurtosis"][matrix]

gives a multivariate kurtosis coefficient for matrix.

Details and Options

ResourceFunction["MultivariateKurtosis"] is a univariate measure of kurtosis for multivariate data.
ResourceFunction["MultivariateKurtosis"][matrix] is equivalent to where matrix={x1,x2,…,xn}, Mean[matrix] and Σ is the estimated population covariance matrix.
For a matrix with p columns, a value of the multivariate kurtosis coefficient close to p (p+2) indicates approximate multinormality.
