Re: Trend and Seasonality

Why don't you post the data to the List ... indicating the beginning
date .. and let's see if there are any posters out there ( besides me
! ) who can help you ...

By the way you don't want to rempve anything ...not trend .. not
seasonality ..not day-of-the-week ... not week-of-the-year ... not
UNCLEAN observations ...

You want to integrate into one equation and and all of these components
that are statistically significant ... such as

1. ONE OR MORE TRENDS
2. ONE OR MORE LEVEL SHIFTS
3. ONE OR MORE DAY-OF-THE-WEEK EFFECTS
4. ONE OR MORE WEEK=OF-THE-YEAR EFFECTS
5. ONE OR MORE HOLIDAY EFFECTS

If you don't want to release the data to the list .. just send it to me
and I will post the results ...

Nothing to lose ... All to Gain ..
