“…However, a rather obvious solution and one that does not depend on a, the normal vector of the hyperplane is the following: for any a C N: Px,, (x) = cc, or 0 (8) for some constant c,z, independent of the point xei e {1, ...., N}I'l. In other words, these are distributions that take on zero or a constant value for all possible marginals, px, ( ).…”
