Notes on X-13ARIMA-SEATS Version 1.1, Build 61

New options and features

  • Display an error message and stop the program for the following conditions:
    • If a spec file includes any specs that require modeling (regression, check, estimate, forecast, outlier, or seats), and the spec file makes no provision for modeling (no arima, automdl, or pickmdl).
    • If a spec file includes an arima spec with no model argument.
  • Add d7trendma, the length of the Henderson filter used in the D7 table, to the .udg file.

Fixed defects in previous versions

  • Fix the missing data and value in .rts file when the estimate spec includes save = rts, ASCII version.
  • Fix the issue when running with the -s command and the estimate spec does not include save = rts, ASCII version.
  • Fix the incorrect key value for the significance test for user-defined regressors in AICC testing; change label aictest.cvaic.e to aictest.cvaic.u for the AICC test value for user-defined regressors.
  • Correct the regression matrix constructed by the chi2test option in the regression if the user-defined holiday regressors are removed from the model.
  • Correct the program output for AICC testing when a p-value for AIC testing is specified.
  • Fix the error message that indicates that the original series ends the month before the start date of the original series when the x11regression spec is included.
  • Fix the error of the history analysis not being performed when the history spec includes print = none.
  • Correct some text typos.
