I have known the reason why they are different.

Hello everyone:
I'm making a model comparison. I use fit command to get the forecast values and _se series, but I get different results by using the formula se=SD/N^0.5. Where is the problem?

Who knows the second seasonal difference command in Eviews？

Hell all,

I was trying to test an ARCH effect for an ARIMA model using Correlogram Squared Residuals, but I found that there was no p-value in front of 1-4 lags,why? I am very worried about it.

Hi,how did you resolve your question?Could you tell me?

Dear all:
how to reset the upper and lower bounds of the default value(95%) of cross correlation in Eviews? Thanks in advance.

Really? dear Eviews Gareth,i am a newbee and maybe my question make fun of you，but your confirmation can encourage me to continue to use Eviews，thank you again

http://www.eviews.com/Learning/timeseries_c.html Dear EViews Gareth： Thanks for your reply, in my examples,i type in equation blank(i don't know its correctness): y c x x1 ar(1) ma(1) ,but the variable coefficient prob. were not significant entirely，so i couldn't follow the next step for testing th...

Dear all:
please allow me to ask a small question if c is must be when input an arma model in eviews? Or can delete it if its p-value is not significant in results? Many thanks.

Dear all：
I‘m making a ARMAX model with two exogenous variables(e.g.x,x1),y is output series,I have determine the ccf plot between x-y pairs and x1-y pairs, and lag=0 and 1 respectively,then what should i input in eviews for a armax model? please help and guide me.Many Thanks.

Typically, white noise should show higher numbers in the column.

You did me a great favor，thank u for ur warm heart again，a good person.

I am running a ADF test in Eviews，the results like the attachment(I(1))，but i don't decide the p and q value for ARMA model？Anyone knows? Is this white noise? How to judge the white noise series in Eviews? I would greatly appreciate the help.
