WebNov 7, 2013 · In this paper we give some new upper bounds of Fischer’s inequality and Hadamard’s inequality for a subclass of MathML -matrices and extend the corresponding results due to Zhang and Yang (see [ 11 ]). 2 Some lemmas To avoid triviality, we always assume MathML. We will need important Sylvester’s identity for determinants (see [ 12 ]). 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.

WebIsoperimetric inequality. The Fisher information matrix plays a role in an inequality like the isoperimetric inequality. Of all probability distributions with a given entropy, the one whose Fisher information matrix has the smallest trace is the Gaussian distribution.

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 the design of experiments such as studying the differences among several different varieties of plants, under each of a number of different growing conditions, called blocks.
