4. Forecast the values in the given series using a 3 × 3 double moving average (DMA)
method.
5. Forecast the given y, values using Brown's Smoothing (DSE) method with a 20%
smoothing constant and a simple initialization (i.e. T, = y1,
and ß, (1) = 0.)
6. Forecast the y; values in the given series using Holt's Smoothing (LSE) method
with a = y = 0.2 and a simple initialization ( T, = y1, and ß1(1) = 0).
