It is well known that the correlation matrix has a central role in the analysis of multivariate data. The inverse of the correlation matrix, however, also has important interpretations. An exposition ...

In this paper, the properties of the generalized inverse of an arbitrary incidence matrix are examined in connection with the properties of the network flows in the corresponding directed graph and a ...

The COSAN statement constructs the symmetric matrix model for the covariance analysis mentioned earlier (see the section "The Generalized COSAN Model"): The number of rows of the first matrix in each ...
