Create prediction expression display based on column formula

MathStatChem

I would like to create a formatted prediction expression, based on a column formula, in a custom report window.  When I fit a linear model using Fit Least Squares, in the model report, I can turn on the display of the prediction expression, which displays a formatted "picture" view of the equation.

 

I can then save the equation to the data table as a column with a formula.  

 

Now I want to select that column and display a prediction expression for the formula saved to the column, all by itself, in a new report window.  

 

Is there a way to do this with JSL?

If you're looking for a picture of the prediction expression you can use Expr As Picture().

 

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Drug.jmp" );
obj = dt << Fit Model(
	Y( :y ),
	Effects( :Drug, :x ),
	Personality( Standard Least Squares ),
	Emphasis( Minimal Report ),
	Run
);
obj << Prediction Formula;


New Window( "Example",
	Lineup Box( N Col( 1 ), spacing( 10 ),
		Text Box( "Column Formula" ),
		Border Box( Left( 10 ), Right( 10 ), bottom( 10 ), top( 10 ), sides( 15 ),
			Expr As Picture( dt:pred formula y << get formula )
		)
	)
);
