Magnus, Jan R.; Sentana, Enrique Zero-diagonality as a linear structure. (English) Zbl 07270031 Econ. Lett. 196, Article ID 109513, 4 p. (2020). Summary: A linear structure is a family of matrices that satisfy a given set of linear restrictions, such as symmetry or diagonality. We add to the literature on linear structures by studying the family of matrices where all diagonal elements are zero, and discuss econometric examples where these results can be fruitfully applied.
