Make breakthrough improvements to your product and process with Design-Expert software. Screen for vital factors and components, characterize interactions and, ultimately, achieve optimal process settings and product recipes. Set flags and explore contours on interactive 2D graphs; then visualize the response surface from all angles with rotatable 3D plots. Finally, maximize desirability for all your responses simultaneously and overlay them to see the “sweet spot” meeting all specifications. Design-Expert makes it incredibly easy to apply powerful multifactor testing tools. Give it a try to see what it can do for accelerating your research and making it a huge success.View License Options Free Trial
When results can only be binomial (0 or 1; pass or fail) standard model-fitting falls short. Logistic regression works far better by predicting the probability of success or failure, as shown in the plot of a surface-to-air (SAM) missile test.
“The development work that we do at my company often requires 0/1 assessments. This will be a tremendous help for us.”

Experiments that combine mixture components (such as a cake recipe) with process factors (baking conditions, for example) require too many combinations when fitted to traditional crossed (mixture x process) models. By eliminating superfluous high-order terms, KCV models greatly reduce the number of required runs, with appreciable savings in time, materials and money.
View the interactive half-normal and Pareto plots simultaneously while selecting factor effects for a a dynamic assessment of your experimental results.
"In my opinion, among all the software available for DOE, Design-Expert is the most friendly and complete package; I am a big fan of it."
