If no forecast value for the first period is given, the standard assumption is to set the first forecast equal to the first actual value, expressed as $F_1 = A_1$. This provides a starting point for the exponential smoothing calculations.

Conditions: No initial forecast value is provided for the first period.; You are beginning an exponential smoothing calculation.
