About Eliminating Insignificant Variables
I am running a regression with many independent variables. Some of them are insignificant. What I need to do is to eliminate the most insignificant variable --> see the result --> eliminate the most insignificant variable --> repeat until all variables remaining are significant. Is there any build-i...

Re: A Question about Forecasting
EViews does not have a function to automatically forecast x_(t+1). Think of it this way, if EViews could automatically forecast X then it could also automatically forecast y, and you wouldn't have needed to build a model in the first place. Thank you for your reply. So I will try to build a model (...

A Question about Forecasting
I have used my data from 1997 to 2012 to estimate the following structural model: Yt = Beta1 + Beta2*Xt If I want to forecast the value of Y in the next period (Yt+1), is there any function in EViews to do that? I understand that I need to know the value of X in the period t+1 first. But does EViews...

Re: About Renaming Many Series
Thank you very much for the code.
May I ask one more thing? How should I write the code to do the rename if what I have is 24 matrix instead of 24 series? I cannot form a group for matrix. Thanks.

Re: About Calculating Quintiles
Thank you so much for your confirmation.Note also that there are various options for defining the computation of the quantiles. The default may not line up with what Excel does, but there may be an option that will do so.

About Renaming Many Series
If I have 24 series and their names are as follows:
alpha_1999_m1
alpha_1999_m2
alpha_1999_m3
.

alpha_1999_m12
alpha_2000_m1
alpha_2000_m2
alpha_2000_m3
.

alpha_2000_m12
I want to rename them to alpha_1 alpha_2 .... alpha_24.
How can I write program code to do it? Thank you!

About Calculating Quintiles
I am writing programmes to calculate quintiles for a matrix. I found that @quantile maybe useful. May I confirm that the following command can calculate 20% quintile with the name "quintile_1"? scalar quintile_1 = @quantile(xxx, 0.2) xxx is the name of the matrix I am not sure what I have ...

Re: Transpose of a group view programmatically
group_name.sheet(t) How can I make them become separate series after "transpose"? To me, it seems that the "transpose" is only for visual function. When I click the button "transpose", the group is transposed. But the data is not actually changed. No news series are cr...

Re: How to Create a Series from Other Series
Thank you for your reply. In fact, what I need to do is to calculate quintiles for the 20 series of each month. That means for 1999m1, I need to calculate the quintiles of that 20 observations across series. I need to calculate them in a row-wise way. However, I found that @quantile cannot do it in ...

How to Create a Series from Other Series
I have 20 times series, from 1999m1 to 2011m12. How can I create a new series by programming containing only the first observations of these 20 series? This new series should only contain 20 observations. Thank you.

How to Calculate Quintiles for a Group
I have a group of 20 series. The group called alpha. It looks like this: Alpha_1 Alpha_2 ..... Alpha_20 2000m1 -1.24 NA ..... -1.31 2000m2 0.59 NA ..... -3.51 . . . . 2011m12 0.12 0.55 ..... -2.41 If I want to calculate the quintiles month by month, how can I do that? That means I want to calculate ...
