Oneway(

	Mean Diamonds( 1 ),
	Comparison Circles( 1 )
);
The script begins with a call to the Oneway() function, which returns a Oneway object.
The parentheses after the Oneway() function contain arguments that tell the Oneway function how to make the object.
The first two arguments, Y and X, are required at launch.
The next four arguments are optional: Each Pair, Means, Mean Diamonds, and Comparison Circles.
oneObj = Oneway(
	Y( :height ),
	X( :age ),
	Each Pair( 1 ),
	Means( 1 ),
	Mean Diamonds( 1 ),
	Comparison Circles( 1 )
);

Click Run Script .
This creates the Oneway object and sets the variable oneObj. Now, send a message to tell the platform to turn on the Unequal Variances report.
4.
At the end of the script, add the following line: oneObj << Unequal Variances(1), as shown here:
oneObj = Oneway(
	Y( :height ),
	X( :age ),
	Each Pair( 1 ),
	Means( 1 ),
	Mean Diamonds( 1 ),
	Comparison Circles( 1 )
);
oneObj << Unequal Variances( 1 );
rep = Report( oneObj );
rep["Oneway Anova"] << Close( 1 );
rep["Means Comparisons"] << Close( 1 );
The Report() function returns the report object for the Oneway platform, and stores a reference to the report in the JSL variable called rep. You can send messages or perform actions on the report object, such as closing specific report outlines.
If you close the Big Class.jmp sample data table at this point and then try to run the script, you are prompted to open a data table. A best practice is to precede the call to the Oneway platform with an Open() function to open the associated data table each time the script is run.
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
oneObj = Oneway(
	Y( :height ),
	X( :age ),
	Each Pair( 1 ),
	Means( 1 ),
	Mean Diamonds( 1 ),
	Comparison Circles( 1 )
);
oneObj << Unequal Variances( 1 );
rep = Report( oneObj );
rep["Oneway Anova"] << Close( 1 );
rep["Means Comparisons"] << Close( 1 );
