10 highly intelligent features that make the most from every experiment
Stat-Ease software provides powerful tools for design of experiments (DOE) with a great deal of intelligence baked in. Here are 10 “smart” features that make DOE easy for our users. From bottom to top (ordered by DOE phase: design, modeling, optimization, and confirmation), every one of them provides great value.
Here we go—the countdown begins!
- Factorial design-building wizard guides you to right-sized experiments via a ‘heads-up’ on power to detect important effects despite the variability of run, sample, and test.
- Optimal design builder’s exchange algorithm delivers a finely crafted experiment customized per your specifications.
- Preset lineup of near-zero effects on the half-normal graph of factorial effects makes it easy to see those that merit selection.
- Scoring system for polynomial models suggests just the right 'Goldilocks' level that does not underfit or overfit your results.
- Box-Cox plot studies your model residuals and recommends whether or not to apply a transformation for a better fit and advises which one will do best.
- Detection of non-hierarchical models and, if you agree to fix this, the needed terms get added back for a well-formulated polynomial.
- Application of a curvature test to two-level factorial designs with center points with advice on how to augment the design if significant.
- Annotations on statistical outputs that explain them in plain English and provide advice on what to do when they go awry.
- Numerical search using a highly effective variable-size simplex algorithm finds the most desirable combination of factor settings and/or component levels meeting all your goals for process efficiency, product efficacy, and cost reduction.
- Confirmation tool smartly updates the prediction interval based on the number of follow-up runs at your chosen setting.
Finally, one bonus feature in Stat-Ease software that will make you more intelligent: screen tips via the lightbulb icon (click the >> chevron if showing) next to the Help bubble. This will show interesting information about each feature on the screen for you to understand the underlying statistics.
