CUSUM Control Chart

BrianK — Fri, 09 Jun 2023 23:27:06 GMT

hi guys,

If I take the data set from the sample data library "Engine Temperature Sensor.jmp." and run the script below, I detect a shift at datapoint 26. What I would like to do is to modify the script below,so upon a shift detection only, it would automatically do something (example trigger an email, or write to a file ) flagging a shift was detected and on which data point the shift occurred?

Any ideas on how to achieve this?

Thanks

Brian..

CUSUM Control Chart(
	Y( :Y ),
	Sigma( 5 ),
	SendToReport(
		Dispatch( {"CUSUM Chart"}, "2", ScaleBox, {Min( -10 ), Max( 10 ), Inc( 5 ), Minor Ticks( 1 )} ),
		Dispatch( {"CUSUM Chart"}, "CUSUM Control Chart Plot", FrameBox, {Frame Size( 1136, 644 )} )
	)
);

Challenge Accepted

I wonder if its possible to use the standard control chart alarm scripts to catch the flag and then launch an action?

Maybe...

I'm happy to report - In JMP 16, we added alarm scripts for CUSUM charts. This allows you to trigger warnings or other actions to occur when a shift is detected.
