question 75

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, $\tilde { C } _ { t }$ = 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.
