Hello! I need help please! Anyone know how to work with weekly data
ARIMA-X12 is that it only works for me monthly data
8:51 p.m.
X12 -Arima and similar programs cover only monthly and quarterly data. As
there are 52 weeks plus one day in a year, weekly data are not strictly
periodic. Cleveland and Scott (2007), Seasonal Adjustment of Weekly Time
Series with Application to Unemployment Insurance Claims and Steel
Production, Journal of Official Statistics, Vol.23, No.2, 2007. pp. 209-221
deals with the seasonal adjustment of weekly time series.
Best Regards
John Frain.

There's no problem with estimating an ARIMA model on weekly data in
gretl, and you can even have a "seasonal" component (though
estimation may take a while). It's just that there's no standard
way of carrying out seasonal adjustment of weekly series.

Salvador:
there are two package functions in gretl which you may use for testing
seasonal unit roots for weekly data. You may take it from
File->Function files-> On server, and their names are GHegy and
