dc.description.abstract	The purpose of this note is to characterize all situations in which a linear combination of two commuting tripotent matrices is also a tripotent matrix. In the case of real scalars and real symmetric matrices, this problem admits an interesting statistical interpretation. Namely, it is equivalent to the question of when a linear combination of two quadratic forms in normal variables, each distributed as a difference of two independent chi(2)-variables, is also distributed as such a difference.
