Estimating process capability index Cpm using a bootstrap sequential sampling procedure
journal contribution
posted on 2010-01-01, 00:00 authored by Lasitha DharmasenaLasitha Dharmasena, P Zeephongsekul, P CastagliolaConstruction of a confidence interval for process capability index CPM is often based on a normal approximation with fixed sample size. In this article, we describe a different approach in constructing a fixed-width confidence interval for process capability index CPM with a preassigned accuracy by using a combination of bootstrap and sequential sampling schemes. The optimal sample size required to achieve a preassigned confidence level is obtained using both two-stage and modified two-stage sequential procedures. The procedure developed is also validated using an extensive simulation study.
