How to save ARIMA formula from script?

Question

Hello, All

Is there an efective way to automatically save predictive formulas of ARIMA models?

Here is what I am trying, but the code does not work:

Data = Time Series(
	X( :RowNO ),
	Y( :Name( "8_LIMITS" ) ),
	ARIMA( 1, 1, 4, No Intercept( 1 ) ),
);

Data << (curve[1]  << Save prediction formula);

Any help will be appreciated!

The data are saved to a new table because includes the forecasted predicted values in addition to the actual values.  However, all you have to do is to use a table join to add the data from the new table back to the original data table.

Hi,

I tried this script, but it keeps saving the predicted values on a different datatable.

Is there a way to save it to the same data table, in a new column?

Thanks!

Here is the example from the Scripting Index on how to do that: Help==>Scripting Index==>Time Series==>ARIMA==>Save Prediction Formula Names Default To Here( 1 ); dt = Open( "$SAMPLE_DATA/Time Series/Steel Shipments.jmp" ); obj = Time Series( Y( :Steel Shipments ) ); obj2 = obj << Arima( 1, 0, 0 ); obj2 << Save Prediction Formula;
