Historical Yield data
How is historical yield data incorporated into the forecasting model?
Thank you for your question. Historical yield data are used to calibrate the model. The direction and size of the effect of each factor is determined by comparing the historical yields to the amount of rainfall, temperature, evapotranspiration, location, and other factors. These effects are then used to create the forecast.
The yield data was collected from USDA NASS, from 1500 major corn-producing counties between 2001 and 2016.
