QUESTION:
A monthly time series is shown in the table to the right.
a. Calculate the missing values in the exponentially smoothed series using w = .5.
b. Graph the time series and the exponentially smoothed series on the same graph.
ANSWER:Step 1 of 3
a) We know that the exponential smoothed series, for weight, w, is calculated as
where is the exponential smoothed value at time period t,
is the actual value at time period t and
is the exponential smoothed value at time period 1 -1.
Here the initial smoothed value as
