Can anyone tell me how the eigenstructure table, a property of linear
model fit, is computed? I can't find the details of the computation in
Furthermore, the documentation seems wrong. It is an easy verification
that the eigenvalues listed in the eigenstructure table are those of the
_data_ correlation matrix, rather than of the _parameter_ correlation
matrix. (I used the well-known Hald data.)
Or am I making a foolish mistake?
