ON THE ESTIMATION OF σ AND THE PROCESS CAPABILITY INDICES Cp AND Cpm
Published online by Cambridge University Press: 01 April 1999
Abstract
We consider the problem of estimation of the standard deviation σ and the process capability indices Cp and Cpm for a normally distributed process. The problem is addressed with the objective of obtaining optimal estimators under the classic criterion of minimum variance unbiased estimation, as well as under the Pitman measure of closeness.
