description | The capability indices are widely used by quality professionals as an estimate of process capability. Many process indices have been proposed in last few years. A process capability index Cpmk is a generalized version of the existing indices confidence interval estimate for Cpk is defined. A series of Cp, Cpk, Cpm. In this paper the Percentile-t bootstrap (PTB) simulations using Weibull distribution with different parameters and sample size for the index Cpmk was undertaken to compare the performance and reliability of bootstrap method and the effect of parameters of Weibull distribution (shape and scale). |
