Using Census Bureau's X12 ARIMA within EViews

[kjd31]

How do I seasonally adjust my data in the same fashion the US Census Bureau does using X12-ARIMA within EViews?

Thanks in advance.

Open the series, click on Proc->Seasonal Adjustment->X12.

Of course you're better off using X13. Here's a demo of how to do that: http://www.eviews.com/EViews8/ev8ecx13_n.html

Hello, I have tried to use Census X13 and I get the following error:

NOTE: Unable to test AO2010.Jan due to regression matrix singularity.
The effect of this outlier is already accounted for by other regressors
(usually user-specified or previously identified outliers).
***********************************************************************
ERROR: Estimation failed to converge -- maximum iterations reached.
Rerun program trying one of the following:
(1) Allow more iterations (set a larger value of maxiter).
(2) Try a different model.
See Section 5 of the X-13ARIMA-SEATS Reference Manual for more discussion.

Where can I go from here? I need to seasonally adjust my data. Please help
