How can I save the "Stepwise History" into a data table using JSL

frits_quadt

I am trying to save the "Stepwise History" results from the "Fit model" platform into a data table using the
following script:

obj = Fit Model( Y( :Y ), Effects( :X1, :X2, :X3, :X4, :X5, :X6, :X7, :X8, :X9, :X10, :X11, :X12, :X13, :X14 ), Personality( "Stepwise" ), Run( Stopping Rule( "P-value Threshold" ), Prob to Enter( 0.2 ), Direction( "Mixed" ) ) ); obj << go;

r = obj << Report; dt = r[Table Box( 4 )] << Make into Data Table; Close(dt,Save("Testsave.JMP"));

The reult is a data table with the column names from the stepwise history, but with zero rows. So the information I need for the rest of my analysis is not in the table, while the report does show the history.

Does anyone have an idea to get this working?

You need to "Finish" the platform.  See script below:

Names Default To Here( 1 );
origdt = Open( "$SAMPLE_DATA\semiconductor capability.jmp" );

obj = origdt << Fit Model(
	Y( :NPN1 ),
	Effects(
		:PNP1,
		:PNP2,
		:NPN2,
		:PNP3,
		:IVP1,
		:PNP4,
		:NPN3,
		:IVP2,
		:NPN4,
		:SIT1,
		:INM1,
		:INM2,
		:VPM1,
		:VPM2,
		:VPM3,
		:PMS1,
		:SNM1,
		:SPM1,
		:NPN5
	),
	Personality( "Stepwise" ),
	Run( Stopping Rule( "P-value Threshold" ), Prob to Enter( 0.2 ), Direction( "Mixed" ) )
);

obj << go;
obj << finish;
r = obj << Report;

dt = r["Step History"][Table Box( 1 )] << Make into Data Table;
Close( dt, Save( "Testsave.JMP" ) );
