3-D Inverse with Statistics

Equation 1.36 Repeated as equation 11.9 is used as the basis for computing both network accuracy and local accuracy standard deviations. If the submatrices on the upper right and lower left are zero, the computed answer will be network accuracy. Local accuracy is obtained if the full covariance matrix is used.

Network accuracy standpoint to forepoint is computed assuming no correlation between points. Local accuracy is computed using the full covariance matrix (including correlation input by user).
