A note on positive semi-definiteness of some non-pearsonian correlation matrices
Mishra, SK - Volkswirtschaftliche Fakultät, … - 2009
-definiteness are required. Our investigation finds that while Spearman’s rho, Blomqvist’s signum and Bradley’s absolute r make positive … semi-definite correlation matrices, Shevlyakov’s median correlation very often fails to do that. The use of correlation …

A new neural network for solving quadratic programming problems with equality and inequality constraints
Yang, Yongqing; Cao, Jinde; Xu, Xianyun; Hu, Manfeng; … - In: Mathematics and Computers in Simulation (MATCOM) 101 (2014) C, pp. 103-112
A new neural network is proposed in this paper for solving quadratic programming problems with equality and inequality constraints. Comparing with the existing neural networks for solving such problems, the proposed neural network has fewer neurons and an one-layer architecture. The proposed...

The nearest correlation matrix problem: Solution by differential evolution method of global optimization
Mishra, SK - Volkswirtschaftliche Fakultät, … - 2007
Correlation matrices have many applications, particularly in marketing and financial economics - such as in risk management, option pricing and to forecast demand for a group of products in order to realize savings by properly managing inventories, etc. Various methods have been proposed by...

On generating correlated random variables with a given valid or invalid Correlation matrix
Mishra, SK - Volkswirtschaftliche Fakultät, … - 2004
In simulation we often have to generate correlated random variables by giving a reference intercorrelation matrix, R or Q. The matrix R is positive definite and a valid correlation matrix. The matrix Q may appear to be a correlation matrix but it may be invalid (negative definite). With R(m,m)...
