Recorded Webinars:
This webinar upgrades robustness considerations previously discussed for characterization via factorial design to the optimization phase of process or product development. It lays out response surface methods (RSM) that identify regions within the design space that not only meet all response specifications, but also minimizes variation caused by wandering factor settings and extraneous noise factors. Attend this webinar to learn advanced RSM tools such as propagation of error (POE) to discover the robust high plateaus of performance.
This presentation makes the case for modeling both mean and standard deviation to achieve on target results with minimal variation. It demonstrates benefits via examples where experimenters took advantage of making multiple measurements for every run in their design. Newcomers to statistical design of experiments (DOE) often overlook this opportunity to achieve more robust operating conditions. Attend this webinar to master DOEs aimed at meeting specifications and doing so with utmost reliability.

The goal of robustness studies is to demonstrate that our processes will be successful upon implementation in the field when they are exposed to anticipated noise factors. Join this webinar to learn about the assumptions and underlying concepts that need to be understood when setting out to conduct a robustness study, and what kind of design you need to fit each situation.
Building up from the Mixture DOE Crash Course, this webinar explains how formulators can create experiment designs that combine mixture components with process factors, include categorical factors, and deal with hard-to-change variables.
This presentation provides practical aspects for combining mixture, process and categorical variables into one optimal experiment-design using innovative "KCV" models. Learn about structuring combined designs with a case study on making delightful chocolate chip cookies.
DOE is often presented as a “one shot” approach. It may be more efficient to divide the experiment into smaller pieces, thus expending resources in a more adaptive manner. This sequential approach becomes especially suitable when beginning with very little information about the process, for example, when scaling up a new product. It allows for better definition of the design space, adaption to unexpected results, estimation of variability, reduction in waste, and validation of the results.
Learn how multicomponent and multifactor design-of-experiment (DOE) tools empower experimenters to quickly converge on the quality by design (QbD) “sweet” spot—ingredient and factor settings that meet all specifications at minimal cost. All examples come directly from pharmaceutical industries.
Step up your design of experiments (DOE) know-how via this essential briefing on this multifactor-testing tool. A quick demo lays out what makes statistical DOE so effective for accelerating R&D. Discover how DOE will find your vital few factors and reveal breakthrough interactions.

Discover what you need to know about the diagnostic plots used to validate an analysis of variance (ANOVA). Learn a little about how these plots are made and more importantly, how to interpret the signals that indicate problems with the analysis. In this webinar, we will explore how careful residual analysis can be key to a successful DOE.
By removing known sources of variation such as day-by-day, blocking reduces error in statistical analysis, thus providing higher power for estimating effects and greater precision for fitting response surfaces. The technique, however, encounters limitations in some settings. This quick, 30-minute webinar will discuss the basics of blocking and demonstrate fixed vs. random block effects using the powerful, yet intuitive Stat-Ease® 360 software.

Gleaned from 30 years of running and analyzing designed experiments, these are the things that ultimately lead to great learning opportunities from DOE’s, versus dismal failures with wasted time and effort. Novices to experimentation will benefit from this insightful presentation!
If done properly, design of experiments (DOE) provides huge process improvements via small screening studies. Unfortunately, many experimenters deploy designs such as Plackett-Burmans (PBs) that cannot resolve main effects from potential interactions—these being confounded (aliased). This webinar will evaluate more suitable designs for reliable screening at a minimum number of experimental runs.
In many cases, experimental data is the result of a deterministic simulation rather than a lab experiment. These may be referred to as computer experiments. In other cases, physical experiments may produce low or zero-error response measurements. Such situations need special experimental designs and data analysis tools. See how Stat-Ease 360 fills this need with via space-filling designs and Gaussian process models.

Learn how Python has been integrated into Stat-Ease 360. This tutorial walks through connecting Python, extracting data from SE360, and some other more complex examples.
Learn the differing impacts of running repeated samples or measures, versus replicating runs. Knowledge of the sources of variation in the system and the costs of replicating the DOE run and/or repeating the measure can help one decide which is the best option.
Discover DOE tools aimed at developing systems that hold up when transferred to the field. It features factorials geared for testing many variables in a minimum number of runs—just enough to reveal effects that may lead to failure.
Pat Whitcomb, Stat-Ease founder, illustrates how to take best advantage of designs geared for hard-to-change process settings. While running through a number of case studies with Design-Expert® software, he provides statistical details and practical advice on the pluses and minuses created by the split-plot factor layout.
In this advanced-level webinar, Stat-Ease Consultant Pat Whitcomb discusses robust design, propagation of error, and tolerance analysis. Propagation of error (POE) accounts for variation transmitted from deviations in factor levels. It finds the flats—high plateaus or broad valleys of response, whichever direction one wants to go—maximum or minimum; respectively. Tolerance analysis drills down to the variation of individual units, thus facilitating improvement of process capability.
This talk deals with thorny issues that confront every experimenter: How to handle results that fit badly with your chosen model. Design-Expert software provides graphical tools that make it easy to diagnose what is wrong—damaging outliers and/or a need for transformation.
