How can "Time Series" get the forecast data without showing the graph?

lwx228

The following time series analysis is carried out according to "difference" and "ARIMA".Obtain the prediction data and save the prediction formula.

How to use JSL to realize the time series analysis without displaying the graph window and get the forecast data directly?

Thanks!

dt = Open( "$SAMPLE_DATA/Time Series/Monthly Sales.jmp" );
TS=Time Series(
	Y( :Sales ),
	Difference( 1, 0, 1 ),
	ARIMA( 0, 1, 0 ),
	SendToReport(
		Dispatch( {"Model Comparison"}, "", ScrollBox, {Background Color( 117 )} )
	)
);
TS << Save Prediction Formula;

How to use JSL to directly obtain the prediction data of Step 5?
Thanks!

The Scripting Index shows an example of creating the prediction formula from an Arima.

And if you add the universal "Invisible" to the Time Series() platform I think you will get what you want

TS = Time Series( invisible,  ............

Thank Jim!

dt = Open( "$SAMPLE_DATA/Time Series/Monthly Sales.jmp" );
TS = Time Series(
	invisible,
	Y( :Sales ),
	Difference( 1, 0, 1 ),
	ARIMA( 0, 1, 0 ),
	SendToReport( Dispatch( {"Model Comparison"}, "", ScrollBox, {Background Color( 117 )} ) )
);
TS << Arima( 1, 0, 0, Actual( 1 ), Save Columns );

I saved the prediction formula according to the code in the script guide, which is different from the data I saved in step 4 in the window interface.

I adjusted JSL for different parameters and did not get the result of windowing interface operation.
How to write JSL to get the same results as the window interface.

Thanks Experts!

I searched and searched for community and scripting guides.
I try a variety of methods to get the same prediction data as manually saving the formula column in the window interface.

I look forward to the guidance of the experts.

Best regards.

The following code can enter the window interface:

dt = Open( "$SAMPLE_DATA/Time Series/Monthly Sales.jmp" );
TS = Time Series(
	//invisible,
	Y( :Sales ),
	Difference( 1, 0, 1 ),
	ARIMA( 0, 1, 0 ),
	SendToReport( Dispatch( {"Model Comparison"}, "", ScrollBox, {Background Color( 117 )} ) )
);
