Free Webinar: Beyond Extrapolation — Using Additional Inputs to Improve Forecast Accuracy

April 13, 2023 @ 1:30pm to 2:30pm ET

One of the biggest challenges in forecasting is creating accurate forecasts that leverage the variables that impact demand.

Many forecasting processes rely on univariate (single input) models that extrapolate the demand history. Forecast Pro’s Expert Selection mode automates this process and, in many cases, works quite well.

However, univariate models don’t always capture the whole story. If your demand is impacted by external forces (e.g., price, promotions, weather, etc.) then leveraging additional inputs will often improve forecast accuracy.

In this free one-hour webinar Eric Stellwagen will explore different types of model inputs and explain when they can add value. He will discuss the following inputs and illustrate how they are applied using Forecast Pro:

  • Weighting Transformations
  • Analogy Series
  • Event Schedules
  • Explanatory Variables
  • Dummy Variables
