Hello,
I have the student version of Eviews and am trying to make a Seasonal adjustment and know under the student version the only available adjustment I can make is the Moving average methods but when I select it an error comes up that "seasonal adjustment is only available for monthly and quarterly data" My data is quarterly is there possibly something wrong with my format. It has the date example :3/31/1999, 6/30/1999, 9/30/1999. If that's the issue can I change it somehow?
Thanks!!
laura

Re: Seasonal Adjustmetn
That workfile is daily, not quarterly. The discrepancy in the dates are what caused EViews to believe it is daily. In 2005 you have 1st of July as the quarter 2 date, when, obviously, 1st July is in quarter 3, not quarter 2.

I have problems performing X13 Seasonal Adjustment
At first, very much thank you and congratulations for your work. I have leant a lot in the Eviews Forums web pages. I want to perform a Seasonal Adjustment when I follow Proc/Seasonal Adjustment/Census X-13... and the "X-13 Options" window appears and click in X-13 built in regressors I have a dialog where appear "Outliers" and by default there is "Additive". Wich criteria should I follow in order to choose between "Additive", "Level-shift", "Constant level Change", "Seasonal", "Temporary level change" or "Ramp effect"?
In addition, in the "automatic outliers" option appears several "Outlier types". In the "Level shift" one, I am prompted to choose a "Lenght" (by default is 0). The value that I should imput 1-Can be always 0 (ignoring the frecuency of the series, for example)? 2- If not, Which criteria should I follow to imput a value there?
Lastly, In the "ARIMA" section Can I always left the "ARIMA method" and the "Model" dialogs with the default configuration? Should the "Options" dialog be adjusted in correspondence with the series frecuency?
Kind regards,
Reynaldo
