Shewhart p-chart for attribute (Sigma)

WebDesignesCrow

Hi expert,

 

Is there any way to display the calculated sigma (from binomial distribution) in this limit summaries of p-chart for attribute?

Note: I can calculate it manually by using the formula or reverse mathematical operation but rather than work in Excel, I would like to display it on the JMP limit summaries?

 

Thanks! (I'm using JMP 15)

If Sigma Report isn't enough, you can use Insert Into to add new Number Col Box to the Limit Summaries table box

Names Default To Here(1);
dt = Open("$SAMPLE_DATA/Probe.jmp");

obj = dt << Control Chart Builder(
	Show Two Shewhart Charts(0),
	Show Sigma Report(1),
	Variables(Y(:DELL_RPNBR), Phase(:Process)),
	Chart(Points(Statistic("Moving Range")), Limits(Sigma("Moving Range"))),
	Show Control Panel(0)
);

tb = Report(obj)["Control Chart Builder","DELL_RPNBR Limit Summaries",TableBox(1)];
// get/calculate sigma values...
sigma_values = [3,4];
Insert Into(tb, Number Col Box("Sigma", sigma_values), 5);
