Free Statistics Division Webinar Presented in Spanish: Análisis de Capacidad del Proceso (Ppk) en la Ausencia de Normalidad – December 20, 2016 at 9:00 AM Pacific Time

Join the Statistics Division on Tuesday, December 20th at 9:00 – 10:00 AM PST for a webinar to be given by Eduardo Santiago, Technical Training Specialist at Minitab.

El análisis de capacidad de un proceso requiere de la evaluación de la variación y la comparación del desempeño del proceso con respecto a sus especificaciones. Tradicionalmente decimos que un proceso es capaz si la mayoría de las partes que produce se encuentran dentro de especificación, en otras palabras si la tasa de defectos es pequeña. Inicialmente este análisis fue popularizado por Joseph Juran en su Manual de Control de Calidad, y hoy en día la capacidad de un proceso se mide por lo regular en función de su Cpk y Ppk.

A pesar de la simplicidad en el cálculo de dichos estadísticos, la falta de entendimiento de estos métricos de capacidad pueden conducirnos a su malinterpretación o peor aún la manipulación de tales sin haber antes mejorado el proceso. Por lo tanto es importante entender los supuestos necesarios para validar e interpretar los estadísticos de capacidad. En esta presentación, discutiremos cómo validar los supuestos, pero más importante, cómo lidiar con situaciones cuando los supuestos han sido violados.

En este seminario consideraremos tres enfoques para tratar datos que no están normalmente distribuidos:

1) Hablaremos de las transformaciones de Box-Cox y Johnson

2) Discutiremos la utilización de distribuciones no-normales, y por último,

3) Utilizaremos métodos alternos para estimar con mayor exactitud y precisión los estadísticos de capacidad.

The ASQ Statistics Division is proud to announce that the Lloyd Nelson award was presented at this year’s Fall Technical Conference. The award recognizes the paper in the ASQ journal, Journal of Quality Technology (JQT), which has “the greatest immediate impact to practitioners”.

As the editor of ASQ’s Industrial Quality Control, Nelson in the 1960s proposed dividing the magazine into two publications. Eventually, he convinced the board to create the general-interest magazine Quality Progress and the more technical quarterly Journal of Quality Technology. He became the first editor of the Journal of Quality Technology. Nelson was honored in 2001 as one of the first recipients of ASQ’s Distinguished Service Medal. He was named an ASQ Fellow in 1964 and was awarded the Shewhart Medal in 1978. Nelson also served on ASQ’s Awards Board and Shewhart and Deming Medal Committees, and was a long-time member of the Journal of Quality Technology’s Editorial Review Board.

This year, the Lloyd Nelson Award was presented to Russell V. Lenth for his outstanding paper “The Case Against Normal Plots of Effects”, published in Volume 47, Issue 2. Russ attended the Fall Technical Conference in October in Minneapolis to receive the plaque.

The abstract for the award winning paper reads as follows:

When analyzing effects in an unreplicated experiment, normal or half-normal plots of the effects (also called Daniel plots) are a popular way to visualize them and to judge which are active. This article discusses the ways in which these plots can be confusing and misleading. There are other methods available that are less subjective, easier to explain, more powerful, and less likely to be misinterpreted. I recommend against using Daniel plots, even as a supplement to one of these better analyses.

This paper has been given Open Access by the publisher until October 2017 and can be found at the following link:

The ASQ Statistics Division is proud to announce that the Søren Bisgaard award was presented at this year’s Fall Technical Conference. The award recognizes the paper in the ASQ journal, Quality Engineering (QE), with the “greatest potential for advancing the practice of quality improvement”.

Søren Bisgaard, Isenberg Professor of Management at the University of Massachusetts-Amherst, died in Boston on December 14, 2009, after a year-long struggle against mesothelioma. Bisgaard was an expert on quality management and applied statistics who had an international reputation. He was recognized for his work and granted several awards, including the Ellis R. Ott Award (1990), the Wilcoxon Prize (1998), the Shewell Award (1981 and 1987), the Brumbaugh Award (1987, 1995, and 2008), the Shewhart Medal (2002), and the George Box Award (2004). He was a Fellow of the American Statistical Association and American Society for Quality and an academician of the International Academy for Quality. Søren was a strong advocate of quality improvement and was for many years the author of the “Quality Quandaries” column in QE.

This year, the Søren Bisgaard Award was presented to Rick Picard, Michael S. Hamada, Geralyn M. Hemphill, and Robert E. Hackenberg for their outstanding paper “Accounting for Nonrandomly Sampled Data in Nonlinear Regression”, published in Volume 27, Issue 2. Rick Picard attended the Fall Technical Conference in October in Minneapolis to receive the plaque.

The abstract for the award winning paper reads as follows:

We analyze data that are “cherry picked” (i.e., nonrandomly sampled) from a population and are then used for regression modeling and prediction. Nonrandom data are encountered in numerous situations, and the application of standard statistical methods developed for random samples can easily lead to incorrect conclusions. A case study is presented to illustrate the related issues, as well as the repercussions of erroneously ignoring the nonrandom sampling.

This paper has been given Open Access by the publisher through September 2017 and can be accessed at the following link:

Mini-Paper: Big Data Terminology: Key to Predictive Analytics Success
Key Words:
big data, business intelligence, and predictive analytics
With all of the hype surrounding big data, business intelligence, and predictive analytics (with the statistics stepchild lurking in the background), quality managers and engineers who wish to get involved in the area may be quickly dismayed by the terminology in use by the various participants. Singular concepts may have multiple names depending on the discipline or problem origin (business analytics, machine learning, neural networks, nonlinear regression, artificial intelligence, and so forth). Hence, there is a pressing need to develop a coherent and comprehensive standardized vocabulary. Subcommittee One of ISO TC69 is currently developing such a terminology standard to reside in the ISO 3534 series. In addition to the technical statistical-type terms, it could also include a discussion of some of the software facilities in use in dealing with massive data sets (HADOOP, Tableau, etc.). A benefit of this future standard is to shorten the learning curve for a big data hopeful. This paper describes the initial steps in addressing the terminology challenges with big data and offers some descriptions of forthcoming products to assist practitioners eager to plunge into this area.
 Feature: Agile Teams: A Look at Agile Project Management Methods
Key Words:
agile, scrum, project managment
This article presents a discussion of agile project management including scrum methodology. We see tremendous value that can be gained by the use of agile methods along with existing project management frameworks. Although agile lacks a systems focus, the agile principles apply directly to managing smaller projects within enterprise-level initiatives. Analytics and data science projects are often exploratory in nature, require cross-functional teams to work together, and the scope is often developed through team discovery. Thus, we see agile methods as particularly suited to moving analytics and data science projects forward, preventing backlogs and roadblocks that can occur due to uncertainty and poor communication.

Free Statistics Division Webinar: Approaches to Missing Data–The Good, the Bad, and the Unthinkable – December 1, 2016 at 1:00 PM Eastern Time

Join the Statistics Division on December 1st at 1:00 – 2:00 PM Eastern for a webinar to be given by Karen Grace-Martin, statistical consultant, president and founder of The Analysis Factor.

You’ve probably heard about many different approaches to dealing with missing data, and you’ve probably gotten different opinions about which one you should use. In this webinar, you’ll get an overview of:

• the three types of missing data, and how they affect the approach to take
• the common approach that is generally worse than any other
• the easy, common, seemingly bad approach that often isn’t so bad, and the situations when it doesn’t work
• the two approaches that give unbiased results, one that is very easy to implement, but only works in limited situations, and one that is harder to implement well, but works with any statistical analysis.
