Hi,
I am trying to get the same picture as it is in Gujarati's book (Econometrics by Example, 1st edition), page 274.
I am using the datafile 13.6, I generate first difference of the lnclose (as instructed in the text) and I estimate this equation:
dlclose c ar(4) ar(22) ma(4) ma(22)
and get these results.


The text says that once we have a fitted model (I assume the one above), we go forecasting. Hitting the forecast buttom. And now I have a problem, bacause the textbook's text says that eviews will automaticall use the level of the log prices...But in my example it uses the first difference and I don't the picture in the book, because I get the first difference forecast.

The book's image:


What I get:


So what do I do wrong, and how can I get what is in the book (lnclose arima forecast).
Thanks.

you may want to use d(lclose) rather than dlclose.

I first genererate lclose with GEN lclose=log(close)
and then i generate dlclose=d(lclose)

The program doesn't allow me to generate series called d(lclose)....that is the problem, because I can't write d(lclose)=d(lclose)

just
ls d(lclose) c x etc

thanks...did it...didn't know that function..thought I first needed to generate series....
I got what I needed, thanks.
