JSL Test Mean

Jflood — Tue, 14 Oct 2025 04:08:43 GMT

Trying to script a Test Means function in the ANALYZE DISTRIBUTION. I have populated spec limits with target from a separate data. Is there a way to script this either using the stored Target from column properties or from the sheet I loaded the column properties from so I don't have to hardcode the test to value. I am surprised that there does not appear to be a way to just use this value when doing this manually. jmp 18.2.2

Edit (jthi): Added jsl formatting

Distribution(
	Continuous Distribution(
		Column(:"46_F (mm)"n),
		Process Capability(Use Column Property Specs),
		Test Mean(141.88, Wilcoxon Signed Rank(1))
	)
);

This script shows how you can retrieve a spec limit property and pass a desired value as an input to a means test

dt = Open( "$SAMPLE_DATA/Tablet Production.jmp" );

dt:Dissolution << Set Property(
	"Spec Limits",
	{LSL( 70 ), Target( 72.5 ), Show Limits( 0 )}
);

specproperty = dt:Dissolution << Get Property( "Spec limits" );

dt << Distribution(
	Continuous Distribution(
		Column( :Dissolution ),
		Process Capability( 0 ),
		Test Mean( specproperty["Target"] )
	)
);

If this is a feature you would like to have (and JMP doesn't currently have it), you can make a post to JMP Wish List
