Scientific Statistics, Teaching, Learning and the Computer
(1996-06)It is argued that the domination of Statistics by Mathematics rather than by Science has greatly reduced the value and the status of the subject. The mathematical "theorem - proof paradigm" has supplanted the "iterative ... -
Sequential Methods in Statistical Process Monitoring, Chapter 1: Introduction and Chapter 2: Sequential Monitoring of Variances
(1991-05)A CUSUM chart to monitor variability, based on the Wald-Barnard likelihood ratio test, is introduced. A nomogram to aid in the construction of the charts is also presented. -
Sequential Methods in Statistical Process Monitoring, Chapter 3: Design of CUSUM Charts
(1991-05)In this report we show how to design CUSUM charts to monitor process variability. An eight step outline for the implementation of these charts is included. -
Sequential Methods in Statistical Process Monitoring, Chapter 4: Sequential Monitoring of Models, Chapter 5: Summary and Future Research, and Appendix: Table of ARL Values
(1991-05)An extension of the cumulative sum charts based on the Fisher's score function is introduced. This CUSCORE can be used to monitor parameter changes in a model. It is shown that the traditional CUSUM for location is a ... -
A Simple Rule for Judging Compliance Using Highly Censored Samples
(1991-04)A special case of judging compliance is when the effluent limit is set at a level below the method limit of detection (MDL) of the substance being monitored. In many such cases, almost all measurements on the effluent are ... -
Split-Plots for Robust Product and Process Experimentation
(2000-04)Environmentally robust products and processes are designed to be insensitive to variation over the relevant ranges of the environmental conditions in which they need to operate. Split plots frequently provide efficient ... -
Statistical Process Control and Automatic Process Control: A Discussion
(1992)The roles of Statistical Process Control for process monitoring and of Automatic Process Control for process regulation are considered and common misunderstandings discussed. Simple examples are used to show how the ... -
Statistics as a Catalyst to Learning
(1999-06)A discussion on Part I (Box and Liu, 1999) concerning the implications reaised when RSM is considered, as was originally intended as a statistical technique for the catalysis of iterative learning in the manner illustrated. -
Statistics for Discovery
(2002-03)In this paper the question is discussed why investigators in engineering and the physical sciences rarely use statistics. It is argued that statistics has been overly influenced by mathematical methods rather than the ... -
Studies in Quality Improvement: Designing Environmental Regulations
(1986-02)There is a surprising similarity between what SPC provides for industries and the need for constructing sensitive, reliable standards for environmental regulations. -
Studies in Quality Improvement: Minimizing Transmitted Variation by Parameter Design
(1986-02)By properly designing products and taking the inevitable variation in components into account, engineers can minimize the amount of variation that ultimately shows up in finished products. -
Teaching Quality Improvement by Quality Improvement in Teaching
(1991-02)In response to disturbing challenges ahead, leaders at the University of Wisconsin-Madison are committed to transform the institution to a Total Quality University. As a pilot project in the transformation, this paper ... -
Time Series Models for Forecasting Wastewater Treatment Plant Performance
(1996-02)This paper describes a time series modeling procedure that can be useful for calculating predictions, with confidence intervals, of effluent quality one to five days ahead, and it explains how these predictions can serve ... -
Tolerance Analysis Considering Manufacturing Variability and the Cost of Deviating from the Nominal
(1994-05)A number of different formulae for tolerance analysis and synthesis have appeared over the years. This article discusses the interrelationships between alternative formulae, showing how each is best for a specific set of ... -
Tolerancing Mechanical Assemblies Using Computer Aided Design and Experimental Design
(1997-04)Component tolerances for assembled products are often set with the help of the error transmission formula. However, this approach requires knowledge of the partial derivatives of the functional relationship between the ... -
Total Life Models - An Important Tool in Design of Quality
(1993-12)Product quality is far more than "fitness for use" and robustness in the manufacturing process. This paper discusses the phenomena of product quality in the entire product life. It presents a total life model which serves ... -
A Total Quality Improvement Approach to Student Learning
(1997-08)This paper describes a Quality Improvement Instructional Approach whose purpose is to improve the quality of undergraduate education by helping students realize their potential for learning in traditionally-taught university ... -
Total Quality Leadership vs. Management by Control
(1988-02)To survive in increasingly tough markets, top management in American companies will have to forsake their desire to "control" their employees, and instead learn what it means to provide Total Quality Leadership. -
Total Quality: Its Origins and Its Future
(1995-01)This article discusses how an efficient organization is characterized by its knowledge and learning capability. It examines the learning ability of the human animal, the logic of continuous, never-ending improvement, the ... -
Variable Selection or Variable Assessment?
(1995-02)Variable-selection regression methods are oriented towards selecting a single model as the vehicle for further inferences. The appropriate inference about variables not included is unclear - the conclusion that they have ...
