Forecast the outofsample values for every month in the period July June both months
inclusive using only one appropriate exponential smoothing model either simple
exponential smoothing or Holt exponential smoothing models that you think is most
appropriate given the data Your starting value for any parameters should be
Before you begin Exercise lets check that you have the right data! The average
should be
For Simple Exponential Smoothing for the seed of the level use the first observation,
Y
For Holts Exponential Smoothing for the seed of the level use the first observation,
Y For the seed of the trend take the difference of the first two observations Y Y
Once you identify and develop an appropriate exponential smoothing model with the starting values for parameters what are the following numerical values:
The withinsample forecast for January
The outofsample forecast for October
The outofsample forecast for June
