Win X-13 & X-13-Data

Win X-13

Win X-13 is a Windows interface for the X-13ARIMA-SEATS program.

This interface will:

  • Create the input files necessary for seasonally adjusting a series with X-13ARIMA-SEATS.
  • Run X-13ARIMA-SEATS and display the output files.
  • Create a data table with model information and diagnostics from series run in X-13ARIMA-SEATS.
  • Create graphs from X-13ARIMA-SEATS output.

This site contains distribution files and installation instructions for Version 2.5 of Win X-13, officially released in March 2017. Documentation for the program is also available.

New features in this release include:

  • Updates to the spec creation functionality to work with Build 39 and higher of X-13ARIMA-SEATS.
  • Automatically finds new Java executables without user intervention.
  • When running a spec file from the View window, the X-13A-S executable currently provided in the Settings screen is used.
  • Updated the lists of spec arguments available when customizing spec files in the spec creation window.

Win X-13 was designed to run X-13ARIMA-SEATS and X-12-ARIMA Version 0.3. Not all features will work if using previous versions of X-12-ARIMA. Win X-13 does not support the HTML converter used to convert output files to HTML in the X-12-ARIMA program.

If you are using X-12-ARIMA, we strongly urge you to upgrade to X-13ARIMA-SEATS. If for some reason you cannot upgrade, contact the person listed under Support below.

X-13-Data is a tool that can:

  • Convert data from Microsoft Excel to a text file in datevalue format that X-13ARIMA-SEATS can read.
  • Convert X-13ARIMA-SEATS output files in x12save format to a Microsoft Excel file.

The most recent release contains a redesigned user interface for converting X-13ARIMA-SEATS output to Microsoft Excel, allowing users to convert multiple output files into a single Excel file.

With this update, users will now be able to:

  • Convert multiple X-13ARIMA-SEATS output files to a single Microsoft Excel file.
  • Create worksheets organized by series or by file type.
  • Select file types by description or file extension.
  • Select series output to convert from a list of series or list of metafiles (text files often used in X-13ARIMA-SEATS containing a list of series).
  • Customize the order of the selection list of file types to make selecting frequently used file types easier.

X-13-Data now supports the following data frequencies for converting both from Excel to X-13ARIMA-SEATS and from X-13ARIMA-SEATS to Excel: annual, biannual, quarterly, bimonthly, and monthly.

This site contains distribution files and installation instructions for Version 2.0 of X-13-Data, officially released in April 2015. Documentation for the program is also available.
