• Heteroscedastic two-way MANOVA
• Quadratic form of random matrix
• Modified MANOVA test
• Wishart-approximation

For heteroscedastic two-way MANOVA, the so-called modified MANOVA tests proposed recently are too conservative, not powerful and not affine-invariant. In this note, we show how they can be improved and can be made affine-invariant. A real data example and some simulation studies are used to illustrate and demonstrate the methodologies.
