This function accepts a single input source containing a multivariate series. The source is referenced using a SERIES_SPEC or ART_SPEC. When using a SERIES_SPEC, the multivariate series includes the following fields:
- First field is the original series value.
- Second field is the calculated series value from the model.
- Third field is the calculated residual, which is the original value minus the calculated value.
When using an ART_SPEC, the ART must include an ARTFITRESIDUALS layer and the only required ART_SPEC parameter is TABLE_NAME.
