The method calls available to all solver objects.
| Method name | Description |
|---|---|
| pcs | The (optionally scaled) principal component time series (PCs). |
| eofs | The (optionally scaled) empirical orthogonal functions (EOFs). |
| eofsAsCorrelation | The EOFs expressed as the correlation between each PC and the input data set at each grid point. |
| eofsAsCovariance | The EOFs expressed as the covariance between each PC and the input data set at each grid point. |
| eigenvalues | The eigenvalues (decreasing variances) associated with each EOF mode. |
| varianceFraction | The fraction of the total variance explained by each EOF mode. |
| totalAnomalyVariance | The total variance (sum of the eigenvalues). |
| northTest | The typical error associated with each eigenvalue using North’s rule of thumb [16]. |
| reconstructedField | Reconstructs the input data set using a specified number of EOFs. |
| projectField | Projects an arbitrary field onto the EOFs to produce a set of pseudo-PCs. |
| getWeights | The array of weights used for the analysis. |
