Hi.
I calculated the nonparametric Cpk as below.
And JMP shows Cpk as Ppk in the report
(that is, so called Cpk is shown as Ppk in JMP)
However, Cpk 0.667 is equal to;
1) % conformance: 68.27%
Cpk 1 is equal to;
1) % conformance: 95.45%
Thus I can think of this 0.791 Cpk as about 80% of conformance.
Then this is the point where I am confused to the result of the lowest part of the report.
Nonconformance Expected Overall %= 0%?
How can I accept this?
Please let me know how to interpret this.
Thank you.
