Design-Expert® versions

v10.0 [Feb 5, 2016]
Graphs greatly upgraded to more quickly get you the picture of your experimental outcome
Multiple Graphs view (factor profiler): Seeing effects from input variables side by side shouts out their relative impacts.
Multiple Graphs
All Reponses choice in Numerical Optimization: Compare side by side the overall desirability with the individual optimum results so you get the complete view from the peak of performance.
All Responses
User interface far more engaging
Design Wizard provides guidance for less sophisticated users: If you are not sure where to start with your experiment, follow through with this short series of questions to get an answer.
UI
Expanded Undo/Redo option in Design Layout with new viewer toolbox: Oops, you typed in the wrong number, but now that is no problem: get a do-over by pressing the undo button.
Undo/Redo
Computational capabilities greatly improved
64-bit version now available: Take full advantage of the technology built into your CPU for faster performance for statistical calculations, rendering of graphics and so forth.
Math engine retooled for far-faster computations: Why wait?
Optimal builds now run in parallel making them 3 to 17 times faster: Smart!
Designs no longer limited to 32K runs: This frees up very large experiments done via computer
simulations or with robotic apparatus.
Many designs added and made more versatile
Optimal split plots for Response Surface and Combined (mixture-process) designs: Make it far easier as a practical matter to experiment when some factors cannot be easily randomized, e.g., first mix your cakes by batches (hard) and then bake them at varying temperatures (hard) for differing times (easy).
Many Designs
Blocking for Definitive Screening Designs (DSDs): DSDs offer a fast track to optimization (thus in v10 they are provided on the Response Surface tab)—these newly-invented designs are now even better with the option to break them up into blocks.
Restricted Randomization Central Composite Designs (CCD): Convert this tried and true response surface method (RSM) design into a split plot so it can deal with hard-to-change factors.
Historical data choice for Combined designs: Take advantage of all the tools in Design-Expert— evaluation, model fitting, statistics, diagnostics, graphing and numerical optimization—to see if a sweet spot can be found in your collection of happenstance data, even if it includes both process factors and mixture components.
Historical Data
Power and sample size calculator for binomial responses during build: Design an experiment with sufficient runs to be fairly certain that you will not overlook an important discovery.
Modeling tools supercharged
Definitive Screening Designs (DSD) moved to the Response Surface tab where it can be analyzed as a supersaturated matrix for quadratic modeling: DSDs provide a potential shortcut from screening through optimization, so this is a good place to put them—paving the way to apply Design-Expert’s powerful tools for regression modeling.
AICc, BIC and Adjusted R-squared criteria in algorithmic selection: Take advantage of refinements developed by statisticians to produce a better predictive model.
Automatic Model Selection tool for choosing Criterion and Selection method: Let Design-Expert work out what approach will be best depending on type of experiment you conducted.
