WebAug 13, 2024 · In a time-series forecast, we try to predict the value of a measure whose values are time dependent. Most of the time, the algorithms analyze the curve composed from the values of the measure taken at different time. For example, SAC Smart Predict breaks down this signal in elementary components: trend, cycles and fluctuation.
