EllipsoidQuartiles

EllipsoidQuartiles[matrix]
gives the ellipsoidal loci of the quartiles of matrix.
  • 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.
  • EllipsoidQuartiles[{x1, ..., xn}] is equivalent to EllipsoidQuantile[{x1, ..., xn}, {.25, .5, .75}].
