G matrix [General Statistics]
» Is there any role of G-matrix in the calculation of LSM?
Even with one sample modified the model coefficients are changed. G matrix specifies variance-covariance matrix G and it is used to specify subject-specific effects.
With model changed covariance matrix is also changed, thus, you see the difference. Since MIXED statement uses some algos to achieve convergence, some changes in points could be crucial even if they are insignificant for reviewer.
