Multiple Scenarios for Same Model

[AlbertoAlmuinha]

Hi,

Thanks for the amazing package.

In some sectors, it is necessary to perform modeling using three scenarios (baseline, adverse and optimistic). To do this, three new_data must be used in the forecast function to obtain the predictions for each scenario.

Is there an efficient way to obtain the forecasts of the three scenarios and to put them together in such a way that it is easy to plot the three curves on the same plot? Let's imagine that I have a table with more than one model and I need to repeat this process for each of them.

This is possible with fabletools::scenarios() - the function is experimental so it's not well documented yet but you can find an example of it here: https://otexts.com/fpp3/forecasting-regression.html#scenario-based-forecasting
