TY - JOUR AU1 - Bissell, A. F. AB - Quality engineers use capability (or precision) indices to indicate the extent to which a process or machine can satisfy a specification. Like all other parameter estimates based on sampling, such indices are subject to uncertainty. The paper presents simple but effective approximations for standard errors and confidence intervals for some widely used indices. The presentation covers both American and British/European terminology. TI - How Reliable is Your Capability Index?
