Creating Summary Table for Line of Fit?

Hello,

 

I have a script that generates Graphs using Graph Builder and Bivariate in a window. The function is shown below. Sorry if it is confusing, I had to hide the actual column and data table names. Essentially, the data table called upon in the function contains different lot numbers in rows, and different tests in columns.The function generates a graph for each test parameter vs time, and also generates Bivariate analyses for each graph which contain the Linear regression statistics (equation of line, R squared, p-value). 

 

setup = Function({dt}, {Default Local},
	
	dt = Open ( "Product_example.JMP" );
	dt << Select Where(:"Example_column" == "Example_value" );
	cfg1 = EvalList({dt << Data View, { "List of columns would be here" }});
	EvalList({cfg1});
	
);

build_graphs = Function({cfgs}, {Default Local},
	win = New Window( "Product", vlb = V List Box() );

	ncfg = NItems(cfgs);	
	
	for(i = 1, i <= ncfg, i++,
		{this_dt, this_cols} = cfgs[i];
		ncols = NItems(this_cols);
		for(j = 1, j <= ncols, j++,
			vlb << Append(H List Box (
					this_dt << Graph Builder(
						Show Control Panel( 0 ),
						Size( 600, 400),
						Variables(
							X( :"Time" ), 
							Y( Column(this_dt, this_cols[j]) ), 
							Overlay( :"Lot Number" ) 		
						),
						Elements( 
							Points( X, Y, Legend(12) ),
							Line Of Fit( X, Y, Legend(10), Confidence of Fit(0), F Test(1))
						),
						SendToReport(
							Dispatch(
								{},
								"Time",
								ScaleBox,
								{Format( "Fixed Dec", 10, 0 ), Min(0), Max(50), Inc(6),
								Minor Ticks(0)}
								)	
							)
						),
						this_dt << Bivariate(
							invisible,
							Y( Column(this_dt, this_cols[j])),
							X( :"Time" ),
							By( :"Lot Number" ),
							Fit Line( {Line Color( {213, 72, 87} )} )
						)));			
			)
		);
		win		
	);
	

dt = Open ( "Product_example.JMP" );
cfgs = setup(dt);
Show(cfgs);
win = build_graphs(cfgs);
Show(win);
win << Save Journal("Product_example.jrn", embed data(1));

 

I am trying to see if it is possible to create something similar to a summary table which summaries all the linear regression statistics for each Lot Number. For example, Graph Builder allows you to show Elements like F-test (p-value) on top of the graph, but is it possible to store this values in a table rather than on top of the graph? Right now I am generating the Bivariate analysis to get these statistics, because  I could not figure out a way to extract them from Graph Builder. 

 

Just to give an example of what I am trying to accomplish, I attached an image from a different software 'Graphpad Prism'. When you perform an analysis on your data in GraphPad, a results table is generated which contains the line equation, R square, P value, etc.

I'm not sure if this is what you want, but if you use Fit Model and use Lot Number as a By Variable, you'll get a regression model for each lot number.  If you right click in the parameter estimates table for one of the models, choose Make into Combined Data Table.  You can then use Graph Builder to graph parameter values, confidence intervals, p-values, etc. across the different regression models.

Hmm, I'm not sure if this will work. I tried using Fit Model, but there is no option for X variable, and I am trying to do a Y by X analysis.

The X variable goes where the Model Effects are.

Ah interesting, I got it to work. I will try to implement this in my script to replace the Bivariate portion.
