Once the rolling forecast has been implemented, it should be tracked to see if there are any variances between the actual performance and the set targets. I have a question regarding forward-looking moving-window regressions. Using this data, you can experiment with predictive modeling, rolling linear regression, and more. As a result, even if revenuesSales RevenueSales revenue is the income received by a company from its sales of goods or the provision of services. A rolling analysis of a time series model is often used to assess the model’s stability over time. You can update the version of asreg from ssc by """Rolling ordinary least-squares regression.
