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.

Expand, contract, or shift your design space to hone in on an optimal area. DX13's wizard makes this easy for both process and mixture designs. Re-use existing data (or remove some) and make the most out of your experiment!
Use Poisson regression to fit more precise models when the response is count data (discrete, non-negative), such as the number of defects per unit or the number of occurrences per time period.
Easily model any response in various ways to easily compare them. Simply press the plus (+) button on the Analysis branch and try different model reduction methods or transformations. Choose the best analysis for achieving optimization goals.
