TD_EXTRACT_RESULTS retrieves auxiliary result sets stored in an ART. There are different auxiliary layers available in an ART that can be retrieved using TD_EXTRACT_RESULTS. The auxiliary layers are as follows:
  • ARTPRIMARY contains the primary results returned by the function.
  • ARTFITRESIDUALS contains the residual series.
  • ARTFITMETADATA contains the goodness-of-fit metrics.
  • ARTMODEL shows the validation model context.
  • ARTVALDATA is used for the internal validation process.
  • ARTCPDATA is used to plot the cumulative periodogram.
The time series functions that produce ARTs that have multiple layers are shown in the table.
The primary layer is retrieved using a SELECT statement, or TD_EXTRACT_RESULTS referencing the ARTPRIMARY layer.
