Hi all, I am using the forecasting option from GoodData on a linechart and it works great but in the documentation could not find any information on accuracy? We all know that the more data the more accurate it will be, but is there a way to know how accurate it is?

Hi Goran, the forecasting function uses an autoregressive AR-X(p) model to create forecasts of future trends based on your data. Although there is no way to know exactly how accurate it can be (I can imagine this can only be determined retrospectively), its accuracy will depend on how well the underlying assumptions of the model align with the data. More details about smart functions can be found in our documentation here: https://www.gooddata.com/docs/cloud/create-visualizations/smart-functions/
