Tableau allows you to include forecasts in your visuals. Forecasting is the process of pre-predicting what will happen in the future based on past evidence. Although forecasting is, to some part, guesswork, most firms utilize it to help anticipate where the market will go. Forecasts in Tableau are based on complex models that analyze previous trends to help anticipate future outcomes. Tableau employs an exponential smoothing approach in which recent findings are given more weight than older results. Tableau evaluates the outcomes of up to eight distinct forecasting models when creating a prediction to determine which delivers the most remarkable quality results.
