Design and analysis of gauge R&R studies pdf by Douglas Montgomery
making decisions with confidence intervals in random and mixed ANOVA models
This book provides a protocol for conducting gauge repeatability and reproducibility (R&R) experiments, which are required whenever a new test system is developed to monitor a manufacturing process. This protocol—not currently available in other books or technical reports—is used to determine whether the testing system is capable of monitoring the manufacturing process with the desired level of accuracy and precision.
The book presents an up-to-date summary of methods used to construct confidence intervals in normal-based random and mixed analysis of variance (ANOVA) models. Thus, this comprehensive book will be useful to scientists in all fields of application who wish to construct interval estimates for ANOVA model parameters. It includes approaches that can be applied to any ANOVA model, and because it contains detailed examples of all computations, practitioners will be able to apply the methods easily. The book describes methods for constructing two types of confidence intervals: modified large-sample (MLS) and generalized confidence intervals. Computer codes written in SAS and Excel are provided to perform the computations. Appendices are included for readers who are unfamiliar with confidence intervals or lack a basic understanding of random and mixed ANOVA models.
Design and Analysis of Gauge R&R Studies: Making Decisions with Confidence Intervals in Random and Mixed ANOVA Models is directed at two audiences: engineers who conduct gauge R&R studies as part of a measurement systems analysis, and investigators who use ANOVA methods in their research.
