ETS, the smooth series

Postby maxchen » Thu Jul 09, 2015 7:49 am

EViews 9, ver 20150701, 32bit on XP

Code: Select all

!T = 60   '# of obs in estimation
%otb1 = "1/20/2012"
%otc = "2/22/2012"

wfopen J2012-1m2.wf1

delete cocs
smpl %otb1-!T+1 %otb1
freeze(mode=overwrite, oosp) coc.ets(e=e, t=e, modsel=hq, forc=%otc, table=cl, graph=cl, noconv) cocs


data file http://forums.eviews.com/download/file.php?id=3416


bugs and questions
1 option forc: OR (EViews 9 Object Ref.pdf) p550, forc=arg Specify the date of the forecast end point. If omitted, the end point will be the end of the workfile sample. Note that in p551, forc=num Set the length of the out-of-sample forecast. By default the forecast will be until the end of the workfile range.

2 the value in cocs does not match any column in Forecast Comparison Table of oosp. However, in EV 9 ver 20150624, cocs match the column of (M,AD,N), which does not converge


Question: for irregular data, how to do with "seasonal specification"

1) Noted, will fix.
2) Can't replicate - when I run your program, the values i COCS are a constant value of 0.008859, which matches the numbers give in the table for ANN.

The seasonal components of ETS probably doesn't work with irregular data.

Is it possible the reason that I am running in VirtualBox?

I setup a virtual machine of win 7 this weekend, and the result still the same as my previous screenshot.

Could you try copying and pasting the code you put in the first post in this thread into a new EViews program, without going via any other package?

I did those way every time.

I record just now: https://youtu.be/eNLSY1RUneU
first VM: win 7, brand new install, only EViews 9 (the notepad++ is green, copy into only, no need to setup)
the second VM: XP
