X-13ARIMA-SEATS downloads contain a subdirectory (x13as) with the following contents:

• the program x13as_html.exe (the X-13ARIMA-SEATS executable with HTML output) or x13as_ascii.exe (the X-13ARIMA-SEATS executable with ASCII output),
• a sample input file named testairline.spc,
• and the Reference Manual and PC Quick Reference (in a subdirectory named docs).

Two Icon programs to assist users of X-13ARIMA-SEATS, in a subdirectory named tools:

• genhol.exe (which generates user-defined regressors for moving holidays) with its documentation, genhol.html
• cnvx13as.exe (which converts spec files used with X-12-ARIMA to files that can be used with X-13ARIMA-SEATS), with its documentation, cnvx13as.html.

Downloads contain a subdirectory (x13as) with the following contents:

• the program x13as_html.exe (the X-13ARIMA-SEATS executable with HTML output) or x13as_ascii.exe (the X-13ARIMA-SEATS executable with ASCII output) compiled with the Gfortran compiler,
• a sample input file named testairline.spc, and
• the Reference Manual and Unix/Linux Quick Reference in a subdirectory named docs.

Three pdf files comprise the program documentation: the full Reference Manual; a Quick Reference that provides a brief summary of the X-13ARIMA-SEATS input specifications; and, for the Windows version, a quick guide to running X-13ARIMA-SEATS with the Win X-13 interface. There are versions of these documents for the HTML output and ASCII text output versions of the program, though differences between the two versions are generally slight. The full Reference Manual covers both the Windows and Linux/Unix versions, while for the quick reference, there are different Windows and Linux/Unix versions. Finally, there are compressed archives containing the full and quick reference manuals for the Windows version (one archive for HTML output and one for ASCII text output), and another set containing the full (same) and quick reference manuals for the Linux/Unix version.

• Copy the zip file x13as_ascii-V1-1-B59.zip or x13as_html-V1-1-B59.zip to the drive where you want to install X-13ARIMA-SEATS.
• Uncompress the file - the program will be stored within the x13as subdirectory.

To install the Icon programs:

• copy the zip file toolsX13.zip into the same folder as the X-13ARIMA-SEATS program file.
• Uncompress the file - the utilities will be stored within the tools subdirectory.

• Download one of the compressed archives (such as x13asall.tar.gz).
• Expand the contents of the file using the tar utility, using the following command:
  tar -xzvf x13asall.tar.gz

Note that the executable that is stored in the distribution file was compiled on a Linux system - it may not run on your machine. If this is the case, download the x13assrc.tar.gz file, uncompress the source code and compile it - you will need a Fortran compiler on your Unix/Linux system.

Also note that if you save the x13asall.tar.gz file to a windows machine and then move the downloaded file to a Linux machine, the x13asall.tar.gz file may not retain the .gz part of the file extension. However the file even without that extension will uncompress and extract the required files as per instructions.
