Applications of Proc ESM in SAS 9.2
Source: University of Copenhagen
In this paper the various facilities of Proc ESM in SAS 9.2 will be demonstrated using a dataset of 87789 registrations of the speed of passing cars on a highway near Copenhagen. Proc ESM (for Exponential Smoothing Models) was introduced in SAS version 9.2 as a procedure corresponding to more modern time series analysis than its successor Proc Forecast as the smoothing parameters are estimated and not fixed. Moreover Proc ESM has facilities to accumulate transactional data in various ways and has a broad flexibility in transforming the time series to be forecasted.
