A regression analysis is useful in determining the impact external and internal influences have on your site’s energy patterns. These external and internal influences are referred to as predictor sources. A predictor source is an event that impacts energy demand and usage. A predictor source can include facility activities, internal processes, and weather conditions. The energy data being influenced is referred to as the response source. Response sources are identified when creating a Regression Analysis.
