For example, a matrix that has a pair of identical rows, or a pair of identical columns, does not have a matrix. In such cases the demo implementation will not fail, but instead the demo inverse ...

For a symmetric correlation matrix, the Inverse Correlation Matrix table contains the inverse of the correlation matrix, as shown in Figure 40.14. The diagonal elements of the inverse correlation ...

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 ...
