question 136

Multiple Choice

The time-series multiplicative model is used for forecasting, where $T _ { t } , C _ { t } , S _ { t },$ and $R _ { t }$ are respectively the trend, cyclical, seasonal and random variation components of the time series, and $y _ { t }$ is the value of the time series at time t. The following estimates are obtained: $\hat { T _ { 1 } }$ = 125, $\hat { C } _ { t }$ = 1.03, $\hat { S } _ { t }$ = 1.02, $\hat { R } _ { t }$ = 0.97. The model will produce a forecast of:

• A)122.659.
• B)131.325.
• C)118.980.
• D)127.385.
