gives the ellipsoidal loci of the quartiles of matrix.


  • To use , you first need to load the Multivariate Statistics Package using Needs["MultivariateStatistics`"].
  • EllipsoidQuartiles[matrix] gives a list of the loci of the .25, .5, and .75 quantiles of matrix.
  • EllipsoidQuartiles[matrix] returns a list of Ellipsoid objects centered at Mean[matrix].
  • The semi-axes radii are scaled to contain the fractions .25, .5, and .75 of the sample space.
  • is equivalent to EllipsoidQuantile[{x1,,xn},{.25,.5,.75}].
