bhutanGalit Shmueli, National Tsing Hua University’s Distinguished Professor of Service Science, will be visiting the SAS campus this month for an interview for an Analytically Speaking webcast.

Her research interests span a number of interesting topics, most notably her acclaimed research, To Explain or Predict, as well as noteworthy research on statistical strategy, bio-surveillance, online auctions, count data models, quality control and more.

In the Analytically Speaking interview, we’ll focus on her most interesting Explain or Predict work as well as her research on Information Quality and Behavioral Big Data, which was the basis of her plenary talk at the Stu Hunter conference earlier this year. I'll also ask about her books and teaching.

Galit has authored and co-authored many books, two of which — just out this year — include some JMP. First is Data Mining for Business Analytics: Concepts, Techniques, and Applications with JMP Pro, with co-authors, Peter C. Bruce, Nitin R. Patel, and Mia Stephens of JMP. This first edition release coincides with the third edition release of Data Mining for Business Analytics: Concepts, Techniques, and Applications with XLMiner, with the first two co-authors listed above. As Michael Rappa says so well in the foreword of the JMP Pro version of the book, “Learning analytics is ultimately about doing things to and with data to generate insights.  Mastering one's dexterity with powerful statistical tools is a necessary and critical step in the learning process.”

The second book is Information Quality: The Potential of Data and Analytics to Generate Knowledge, which Galit co-authored with Professor Ron S. Kenett, CEO and founder of KPA and research professor at the University of Turin in Italy (you may recognize Ron and KPA colleagues as guest bloggers on the JMP Blog on the topic of QbD). As David Hand notes in his foreword, the book explains that “the same data may be high quality for one purpose and low quality for another, and that the adequacy of an analysis depends on the data and the goal, as well as depending on other less obvious aspects, such as the accessibility, completeness, and confidentiality of the data.”

Both Ron and Galit will be plenary speakers at Discovery Summit Prague in March. You can download a chapter from their book, which discusses information quality support with JMP and features an add-in for Information Quality, both written by Ian Cox of JMP. You can see a short demo of JMP support for information quality during the Analytically Speaking webcast on Nov. 16.

Whether your analysis is seeking to explain some phenomena and/or to make useful predictions, you will want to hear Galit’s thoughtful perspective on the tensions between these two goals, as well as what Galit has to say on other topics up for discussion. Join us! If Nov. 16 doesn’t suit your schedule, you can always view the archived version when convenient.

9781629596709_frontcoverRonald Snee and Roger Hoerl have written a book called Strategies for Formulations Development. It is intended to help scientists and engineers be successful in creating formulations quickly and efficiently.

The following tip is from this new book, which focuses on providing the essential information needed to successfully conduct formulation studies in the chemical, biotech and pharmaceutical industries:

Although most journal articles present mixture experiments and models that only involve the formulation components, most real applications also involve process variables, such as temperature, pressure, flow rate and so on. How should we modify our experimental and modeling strategies in this case? A key consideration is whether the formulation components and process variables interact. If there is no interaction, then an additive model, fitting the mixture and process effects independently, can be used:

c(x,z) = f(x) + g(z), where 1

f(x) is the mixture model, and g(z) is the process variable model. Independent designs could also be used. However, in our experience, there is typically interaction between mixture and process variables. What should we do in this case? Such interaction is typically modeled by replacing the additive model in Equation 1 with a multiplicative model:

c(x,z) = f(x)*g(z) 2

Note that this multiplicative model is actually non-linear in the parameters. Most authors, including Cornell (2002), therefore suggest multiplying out the individual terms in f(x) and g(z) from Equation 2, creating a linear hybrid model. However, this tends to be a large model, since the number of terms in linearized version of c(x,z) will be the number in f(x) times the number in g(z). In Cornell’s (2002) famous fish patty experiment, there were three mixture variables (7 terms) and three process variables (8 terms), but the linearized c(x,z) had 7*8 = 56 terms, requiring a 56-run hybrid design.

Recent research by Snee et al. (2016) has shown that by considering hybrid models that are non-linear in the parameters, the number of terms required, and therefore the size of designs required, can be significantly reduced, often on the order of 50%. For example, if we fit equation 2 directly as a non-linear model, then the number of terms to estimate is the number in f(x) plus the number in g(z); 7 + 8 = 15 in the fish patty case. Snee et al. (2016) showed using real data that this approach can often provide reasonable models, allowing use of much smaller fractional hybrid designs. We therefore recommended an overall sequential strategy involving initial use of fractional designs and non-linear models, but with the option of moving to linearized models if necessary.

9781629596709_frontcover We want to help scientists and engineers be successful at developing formulations quickly and efficiently. Success requires good strategies to get the right data in the right amount at the right time. That's why we published the book Strategies for Formulation Development: A Step-by-Step Approach Using JMP.

We have worked with formulation scientists and engineers for decades and have seen many different types of formulation development programs. This has shown us what formulation scientists really need to know rather than what is nice to know. Because JMP software is used in the examples in the book, readers get valuable guidance on the software for the proposed methodology. That means JMP users can immediately apply what they learn in the book.

Key takeaways from the book include:

  • Approach the development process from a strategic viewpoint, with the overall end in mind. Don’t necessarily run the largest design possible. An experimentation plan that implements the strategy provides the right road map for developing a successful formulation.
  • Focus on developing understanding how the components blend together. Use designs and models that help find the dominant components, components with large effects, and components with small effects.
  • Use screening experiments early on to identify those components that are most important to the performance of the formulation. This strategy creates a broad view and helps ensure that no important components are overlooked. It also saves significant experimental effort.
  • Analyze both screening and optimization experiments using graphical and numerical methods, which is easily done with JMP. The right graphics can extract additional information from the data.
  • Consider integration of both formulation components and process variables in designs and models, using recently published methods that reduce the required experimentation by up to 50 percent.

This is how you speed up the formulation development process and produce high-quality formulations in a timely manner. Upcoming blog posts will show how to address each of these important issues.

My previous post pondered the term disestimation, coined by Charles Seife in his book Proofiness: How You’re Being Fooled by the Numbers to warn us about understating or ignoring the uncertainties surrounding a number, mistaking it for a fact instead of the error-prone estimate that it really is. Sometimes this fact appears to […]

In his book Proofiness: How You’re Being Fooled by the Numbers, Charles Seife coined the term disestimation, defining it as “the act of taking a number too literally, understating or ignoring the uncertainties that surround it. Disestimation imbues a number with more precision that it deserves, dressing a measurement up as absolute […]

In my previous post Sisyphus didn’t need a fitness tracker, I recommended that you only collect, measure and analyze big data if it helps you make a better decision or change your actions. Unfortunately, it’s difficult to know ahead of time which data will meet that criteria. We often, therefore, collect, measure and analyze […]
