WebIncome inequality increased by 5.1% (1984-2006) and by 4.9% (1986-2006). Consumption inequality increased by 11.0% (1984-2006) and by 3.0% (1986-2006) using our consumption measure defined in subsequent slides.

Proof: Suppose that b < v and let A be the incidence matrix of the design. We can add v – b columns of 0's to A to get a v × v matrix B. Since these extra columns of 0's will not alter the inner products, we must have AAΤ = BBΤ. By taking determinants we see ...

Fisher's inequality is a necessary condition for the existence of a balanced incomplete block design, that is, a system of subsets that satisfy certain prescribed conditions in combinatorial mathematics. Outlined by Ronald Fisher, a population geneticist and statistician, who was concerned with … See more Let the incidence matrix M be a v × b matrix defined so that Mi,j is 1 if element i is in block j and 0 otherwise. Then B = MM is a v × v matrix such that Bi,i = r and Bi,j = λ for i ≠ j. Since r ≠ λ, det(B) ≠ 0, so rank(B) = v; on the … See more Fisher's inequality is valid for more general classes of designs.
