Roll (Rolling Regression)

This thread is about the Roll Add-in that performs rolling regression from a single equation object, letting you store various coefficient or equation statistics from each iteration of the roll.

Change log
  • 2010/02/10 - Initial release
  • 2010/04/19 - Fix for a bug whereby stored coefficients/statistics were being stored at the wrong dates if the start point of the roll was not the first observation in the workfile
  • 2011/08/22 - Added an error message for panel workfiles (which are not supported)
  • 2012/04/11 - Command options are added

Hello I'm new to the forum. I tried to run rolling regression install.prg but got an error. I'm running Eviews 6

EViews Addins require EViews 7.

Hello
I am running eviews 7.1 and am trying to run a rolling regression using the simple roll add-in. The columns have 6080 rows and each 40 rows is for a certain group, so I need to do a regression for each 40 rows. When i run the first set of rows the regression works fine however I then go to add ins, use a window size of 40 and a step size of 40 and a get perfect multi colliniarity warnings (even though the equation is designed to prevent this) and meaningless coefficient output files with 6080 rows. What am I doing wrong? not least what is the sample size I need to enter into the equation box (e.g. to do the first set of rows I entered 1 40)
I have enclosed the output from my first run in case it sheds some light
Many thanks
Sam

The sample box is used to indicate the entire sample that will be used, not the sample for the first roll.

how do I use the add-in once I have installed it?

Open an equation, click on the Add-in menu and select it.

Hi,

Can anyone show me sample codes for using the rolling coefficients(obtained from using the Rolling Regression Add-In in Eviews 7.2) to forecast the dependent variable?

Thank you!!!

Assuming you have a simple linear regression, you'll have to write out the algebra in a series expression manually. Something like:

Code: Select all

series fcast = coef1 + coef2*x1 + coef3*x2

Hi guys,

How to see stored coefficient after running roll add in? (in a table or matrix form)

thanks in advance
