Control Chart Method for Analyzing Staggered Nested Data

Abstract

For standardizing a measurement method, some precision experiments are required to evaluate its precision data. Precision data usually include repeatability and reproducibility, and sometimes include other intermediate precision, i.e. reproducibility within a laboratory. Nested designs are often used for estimating these precision data. For establishing a sampling procedure of bulk materials, nested designs are also required for estimating variance components of variability in various stages. These estimates of variance components enable us to find the optimum allocation in multi-stage sampling.
