In this example, the capability index C pk is computed for the amplification data in AMPS. To examine the accuracy of this estimate, the following statements calculate a 90% confidence interval for C ...

This example illustrates how you can use the OUTPUT statement to compute confidence limits for the capability index C pk. You can request the approximate confidence limits given by Bissell (1990) with ...

Many people sometimes confuse Cmk and Cpk. An easy way to distinguish the two is to remember the ‘M’ in Cmk lets you know ...
