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 << Save prediction formula);
Any help will be appreciated!
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;
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?
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.
