The formula St = wyt + (1 - w)St-1 is used in time-series forecasting with exponential smoothing, where St is the exponentially smoothed time series at time t, yt is the value of the time series at time t, and w is the smoothing constant. The forecasted value at time t + 1 where w = .4 is given by:
a. Ft + 1 = 0.4yt +1 + 0.6St + 1 c. Ft + 1 = 0.4yt + 0.6St - 1
b. Ft + 1 = 0.4yt + 0.6St d. Ft + 1 = 0.4yt - 1 + 0.6St
