Usage of sax12 with X13 Arima

[Sebastian Front]

Dear all,
I wanted to use sax12, but it's based on X12 Arima from Census Bureau. This software is not available anymore, as there is a new version (X13). The page to which papers related to sax12 redirect is unavailable. Therefore a question before I start investing time in getting X13 Arima - is sax12 going to work with x13 arima? If not, is there currently any package available to run seasonal adjustments in Stata?
I know I could download x12 from a third party server, but I am in a big organisation, where installing a software by an IT department can take days and requires a line of approvals. Having the software from Census Bureau would work, having it from whatever "good programs" or similar site is definitely a no-go.
Thanks in advance,
Sebastian

Welcome to Statalist, Sebastian.

We see that

net sj 12-2 st0255

which describes the sax12 package from Stata Journal includes an email address for support for that user-written extension to Stata. That would seem to be the definitive source of advice about compatibility with x13.

If use of sax12 is not possible, you might want to start another topic here with a title like "How to do seasonal adjustment?" and a description of the particular problem you want to solve. Perhaps a simpler approach involving standard time series commands will meet your needs. Alternatively, you may have to install x13 ARIMA and then export your data from Stata into the appropriate format for input to that program, and then bring the smoothed results into Stata for subsequent use.
