How to Pass Variables to the X Parameter in Fit Life by X?

Arthur

Hi everyone,

 

I need to dynamically pass variables to the X parameter in the fit life by x function. The first part of my code generates the analysis report as expected, but the second part only brings up the startup window without a report.

Here’s what my code looks like:

Names Default To Here(1);

dt = Open( "$sample_data/big class.jmp" );

x_var = "sex";
y_var = "weight";

obj1 = dt << Fit Life by X(
	Distribution( Weibull ),
	Nested Model Tests( Location and Scale ),
	Y( Eval(y_var) ),
	X( :sex ),
);

wait(2);

obj2 = dt << Fit Life by X(
	Distribution( Weibull ),
	Nested Model Tests( Location and Scale ),
	Y( :weight ),
	X( Eval(x_var) ),
);

Has anyone encountered this issue or knows how to correctly pass the variables to the X parameter?

 

Thanks!

Please see the following.

Because "Relationship" is missing, the codes is trying to make the best guess based on X. But at the place where the codes checks on X, X is not a valid column yet, in this case. So, providing complete information, the codes don't need to walk into the trap.

 

Names Default To Here(1);

dt = Open( "$sample_data/big class.jmp" );

x_var = "sex";
y_var = "weight";

obj1 = dt << Fit Life by X(
	Distribution( Weibull ),
	Relationship( Location and Scale ),
	Nested Model Tests( Location and Scale ),
	Y( Eval(y_var) ),
	X( :sex ),
);

wait(2);

obj2 = dt << Fit Life by X(
	Distribution( Weibull ),
	Relationship( Location and Scale ),
	Nested Model Tests( Location and Scale ),
	Y( :weight ),
	X( Eval(x_var) ),
);
