Hi, I have a dataset with 35 banks (N) and 2600 trading days (T) each, and I want to test for cross-sectional dependence (which should be there in theory). However, I get the message: Correlation matrix of residuals is singular. not possible with test, r(131); I already searched ...
The square matrix A = (aij) is nonsingular if its determinant is not zero; otherwise the matrix is singular. A matrix A−1 is an inverse of the square matrix A if AA−1 = E in this case, ajk(−1) = Aki/│A│, where Aki denotes the cofactor of aki,. The nonsingularity ...
摘要: Following the work of Tucker, Cooper, and Meredith, image and anti-image covariance matrices from a correlation matrix that may be singular are derived.关键词:covariance singular matrix images anti-images DOI: 10.1007/BF02293555 被引量: 10 ...

A particular attractive feature of the method is that the singular value analysis of the Hankel matrix of autocorrelation functions offers a practical criterion for the decomposition of the data into a signal and a noise part. Some tests of the method are illustrated with experiments on ...
This paper discusses a number of useful measures of correlation, with emphasis on measures which are invariant with respect to rotations or changes in singular values of either matrix. The maximization of matrix correlation with respect to transformations XL and YM is discussed where one or both ...
