In R, we often need to get values or perform calculations from information not on the same row. Hi there, I am running a three-year window regression of operating profit on sales by using quarterly data for each firm over three year window. Just like ordinary regression, the analysis aims to model the relationship between a dependent series and one or more explanatoryseries. An object is the same class and dimension (with an added column for the intercept) as x. The "Roll" Add-In is a simple EViews program that is integrated into EViews, allowing you to execute the rolling regression program from a single equation object.Use the EViews rolling regression User Object: EViews allows us to create a new roll object and store various coefficients or statistics from each iteration of the roll. Here are a few of the ways they can be computed using R. I will use ARIMA models as a vehicle of illustration, but the code can easily be adapted to other univariate time series models.
