Obtaining strings from a group
I put over 200 series together in a group. Is there any way to obtain the title strings from the series? So for example let's say I have a group with 5 variables, say serie01, serie02,...,serie05. If i want to obtain the title of the third series (i.e. "serie03") in a string, how can I ach...

Forecasting formula
I'm working on a project where I have to do a 20-step-ahead forecast. I have a lot of variables (+/- 300). From the equation I can do a 1-step-ahead forecast (static). Is there any way that I can see which formula EViews uses to do this 1-step-ahead forecasts? This will give me insight into how to d...

Re: Loops using strings and scalars at the same time
Thanks for the help! On which page of the help documentation can I find more information about the .add functionality? I was trying to look it up but could not find it. Thanks in advance!

Re: Loops using strings and scalars at the same time
By the way, assuming the code will eventually work, the string will look something like this: string testString = "group01(3) group01(4) group(12)" Now, if I want to regress on these variables I can't state: equation testRegression.ls y testString It will produce an error that testString i...

Loops using strings and scalars at the same time
Hello! I want to make a loop that incorporates both strings and integers. So far I have created a group with a lot of variables (+/- 200). I'm working on a project where p > n, that means I have more variables then observations. There is a method called the LASSO method that chooses some of the vari...

Elastic Net Regression in EViews
Hi, Is there any way to implement the elastic net (a combination of the Lasso and Ridge regressions) in EViews, in which some variables are shrunken to 0 so that they are dropped from the model? The estimation uses the objective function: min L(Beta) = the sum of( (y - X * Beta)^2 + lambda * P(Beta)...

Adjusting sample size
Hello everybody ! I have written a big program in EViews. Now that everything works I want to generalize my program. That means, in stead of manually putting scalars everywhere I want to do it just one time on top of my program. For example: on top of my program I stated: "scalar test = 20"...
