Returns the value of an X-12-ARIMA model output component (e.g., trend, seasonal or irregular).
Syntax
X12ACOMP (model, step, component)
- Model
- Required. Is a unique identifier that designates an X-12-ARIMA model created earlier with the X12 Wizard.
- Step
- Optional. Is the offset (i.e., index) from the beginning of the original time series sample data. If missing, the step is assumed to be 1.
- Component
- Optional. Is an identifier of the output component (1 = SA (default), 2 = Trend Cycle, 3 = Irregular, 4 = Seasonal Factor, etc.). See the help file for a complete list of the supported components.
Value Component 1 Final seasonally adjusted series (d11) (default). 2 Final trend-cycle (d12). 3 Final irregular component (d13). 4 Final seasonal factors (d10). 5 Combined holiday and trading day factors (d18). 6 Combined seasonal and trading day factors (d16).
Warning
X12ACOMP(.) function is deprecated as of version 1.67; use the X13ASCOMP(.) function instead.
Remarks
- The underlying model is described here.
- If the model identifier is invalid or not recognized, the function returns "#VALUE!"
- If the step value is greater than the input data set size, X12COMP returns "#N/A!".
- If the step value is negative, X12ACOMP returns "#VALUE!".
- If the component argument value is not supported, X12ACOMP returns "#VALUE!".
