WebSep 13, 2024 · The lag is a consequence of the exponential smoothing. We could reduce the lag by weighing recency higher, but that may incur a cost elsewhere. We discuss trade-offs involving this in the next paragraph. Next, let’s calculate x ^ ( t +3) at time t = 4. It is f ^ (4) + 3* df ^ (4) = 3.25 + 3*1 = 6.25.
