Calculates the prediction interval(s) for additive forecast based on the historical data using ETS or EDS algorithms. EDS is used when argument period_length is 0, otherwise ETS is used.
timeline (mandatory): A numeric array or range. The timeline (x-value) range for the historical values.
The timeline does not have to be sorted, the functions will sort it for calculations. The timeline values must have a consistent step between them. If a constant step cannot be identified in the sorted timeline, the functions will return the #NUM! error. If the ranges of both the timeline and the historical values are not the same size, the functions will return the #N/A error. If the timeline contains fewer than 2 data periods, the functions will return the #VALUE! error.
