For the yearly U.S. STD data discussed in Example 8.7, use the nine-MMWR-region aggregation

matrix, which is saved as Bookdata set, WW8c-R9, to create the nine-dimensional

aggregate series. Build a nine-dimensional model for the aggregate series and use it to compute

the next three-step forecasts.

For the yearly U.S. STD data discussed in Example 8.7, use the four-STD-region aggregation

matrix, which is saved as Bookdata set, WW8c-R4, to create the four-dimensional

aggregate series. Build a four-dimensional model for the aggregate series and use it to compute

the next three-step forecasts.
