IdtMANOVA extends`"LRTest"`

directly, containing the results of MANOVA tests on the interval-valued data. This class is not used directly, but is the basis for different specializations according to the model assumed for the
distribution in each group. In paticular, the following specializations of IdtMANOVA are currently implemented:

"IdtClMANOVA" extends IdtMANOVA, assuming a classical (i.e., homocedastic gaussian) setup.

"IdtHetNMANOVA" extends IdtMANOVA, assuming a heterocedastic gaussian set-up.

"IdtLocNMANOVA" extends IdtMANOVA, assuming a Skew-Normal location model set-up.

"IdtLocNSNMANOVA" extends IdtMANOVA, assuming either a homocedastic gaussian or Skew-Normal location model set-up.

"IdtGenNMANOVA" extends IdtMANOVA, assuming a Skew-Normal general model set-up.

"IdtLocNSNMANOVA" extends IdtMANOVA, assuming either a heterocedastic gaussian or Skew-Normal general model set-up.
