Define datasubset for the application of Westgard rules

kknudsen

I have a dataset, that I wish to plot in a control chart of JMP v14 (control chart builder) with the purpose of finding out if any of the data points violate any of the Westgard rules. However, I do not neccesarily wish to define mean and SD based on the whole dataset, but only a subset. I have been trying to find a way of doing this, but have not yet been successful. Is there anyone that knows how to do this?

 

Thanks in advance.

Take a look here, in the section 'Specify Control Limits':

 

 "Since we established that the process is in control, we can use these historical limits with new data to see how the new data compares to the existing process. This means we need to specify control limits instead of having JMP calculate them"
