A GENERALIZED FUZZY COVARIANCE MATRIX

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 1995
This paper describes a generalized fuzzy covariance matrix based on the notion of fuzzy similitude and its application to discriminant analysis. It is shown that this generalized fuzzy covariance matrix may be useful in the determination of outliers. It is further noted that the generalized fuzzy covariance matrix may help to distinguish outliers from

Covariance Matrix Simulation

2003
Abstract This chapter develops further the idea of LU decomposition and applies it to the simulation of covariance matrices. The vast majority of cash flow models used to analyze the creditworthiness of structured securities or to investigate foreign exchange risk will include an implementation.
