There are no definite ways to decide this. Basically, we look at the
|
|
|
eigenvalue spectrum and decide:
|
|
|
| (1) |
The 95% significance errors in the estimation of the
eigenvalues is:
|
|
|
If the eigenvalues of
adjacent EOF’s are closer together than this
|
|
|
standard error, then it is unlikely that their particular structures
are
|
|
|
significant.
|
|
|
(2) Or we can just look at the slope of the eigenvalue spectrum.
|
|
|
We would
look for a place in the eigenvalue spectrum where it levels
|
|
|
off so that successive eigenvalues are
indistinguishable. We would not
|
|
consider any eigenvectors beyond this point as being special.
