StatControlCharts.QCCapIndexes Method

void QCCapIndexes(TVec Data, Double LB, Double UB, ref Double p, ref Double CP, ref Double CPK, ref Double[] CPConfInt, ref Double[] CPKConfInt, Double Alpha)

Process Capability indexes p, Cp and Cpk.

#	Name	Description
1	Data	Process data.
2	LB	Lower specification limit. LB and UB are boundaries within which measurements on a product characteristic must lie.
3	UB	Upper specification limit. LB and UB are boundaries within which measurements on a product characteristic must lie.
4	Alpha	Desired significance level.
5	p	Returns calculated significance.
6	CP	Returns capability index.
7	CPConfInt	Returns 100*(1-Alpha) Cp confindence interval.
8	CPK	Returns capability index for uncentred process.
9	CPKConfInt	Returns 100*(1-Alpha) CPK confidence interval.

Result: stored in self (calling object)

Remarks:

Calculates the Process Capability indexes p, Cp(aka CPR) and Cpk(AKA CPRk).
