WebFischer et al. contend that Herrnstein and Murray's data explain, at best, only a limited amount of social inequality in the United States (between 5% to 10%) and that the analysis of the data in The Bell Curve is itself flawed. Subordinate ethnic groups [ edit] In mathematics, Fischer's inequality gives an upper bound for the determinant of a positive-semidefinite matrix whose entries are complex numbers in terms of the determinants of its principal diagonal blocks. Suppose A, C are respectively p×p, q×q positive-semidefinite complex matrices and B is a p×q complex … See more Assume that A and C are positive-definite.
