Forecasting is one of the most universally required (and reviled) business functions in analytics. OBIEE and Data Visualization now have the ability to automatically generate sophisticated forecasts with the click of a mouse. We’ll explain how OBI uses R to construct both exponential smoothing and ARIMA models. We’ll contrast the model choices and review when to use each and go into both how the automated models work as well as more configurable scripts. We’ll also cover some of the most common *gotchas* that we’ve encountered in generating forecasts in real world implementations.
