Question
In simple exponential smoothing satisfying the formula:
$$\hat{x}_{n+1}$$ = αxn + (1 − α)$$\hat{x}_n$$
if α =1, then $$\hat{x}_{n+1}$$ = xn, so the 1-step ahead forecast is just the [...] value.

In simple exponential smoothing satisfying the formula: \hat{x}_{n+1} = αx n + (1 − α)\hat{x}_n if α =1, then \hat{x}_{n+1} = x n , so the 1-step ahead forecast is just the current value.
