Re: Donig the same operation for all the series in a workfile

Unfortunately there is not a way, currently, to get information from an equation about which variables are used in that equation. This will change in EViews 7. A work-around that sometimes is applicable is that you can estimate an equation with just a group as the list of regressors, and then you ca...

Re: Seasonal dummy variables

You cannot use @seas to do this, since @seas only works within 1 year periods (i.e. so the option you can enter on a monthly workfile is 12, not 48). If you would like to do it automatically rather than just manually entering 1s at the appropriate date, something along the lines of: smpl @all series...

Re: Storing sequence of equations for viewing

A sequential/procedural log doesn't really work in a program like EViews, since it isn't a procedural program, as, say, SAS or Stata are.

I guess the closest thing we would have would be, as startz suggested, the spool object. Just print each estimation you do to a spool.

Re: How to enter data into a panel workfile.

If your data is currently in Excel and you want to put it into a panel workfile, then, again, the best way to do it really depends upon what form the data is in inside Excel. However here is one example. A common form of panel data structure in Excel is the following: http://www.eviews.com/Forum_sup...

How to enter data into a panel workfile.

There are a number of different ways to enter data into a panel workfile. Which method works best really depends upon how your data starts out. In this post I'm going to describe a method which converts data that is currently in "pool" form into a panel. For posts on entering data into a p...

Re: Storing sequence of equations for viewing

I guess it sounds like when you're estimating multiple equations, you're simply using the same equation over and over, which is probably not the best way to go. If you use different equations, then they will all exist. You don't have to name them, if you enable multiple unnamed equations, as Startz ...

Re: AR(4) vs SAR(4)

Mathematically you can represent an AR(1) term as: (1-pL)ut where L is the lag operator. An AR(1) AR(2) representation is: (1-p1L - p2L^2)u A seasonal AR term just adds another level to this. An AR(1), AR(2) SAR(1) can be represented as: (1-p1L - p2L^2)(1-sL)u where S is the seaonal AR term. Note th...

Re: Update

EViews 7 will have a feature whereby it will automatically check for updates every time you launch (unless you tell it not to).

Re: Storing sequence of equations for viewing

Not sure I quite follow this suggestion.

The point of EViews is that nothing disappears unless you tell it to. Once you estimate an equation, that estimation is there until you either delete it or close the workfile (without saving).

Re: How do you specify identities in command/batch mode

You can just use the append command to append text, such as an identity, to your model:

Code: Select all

model01.append @identity y=cn+i+g

Re: How do I import data from Eviews to Excel

Unfortunately Microsoft has not (yet?) given Excel the capability to read EViews files. However from within EViews you can save your data in Excel format (just choose File->Save As and then change the file type to Excel).
