• Design experiments that combine mixture components with categorial factors - Case Help

  Hello everyone,  I have recently attended several courses on Mixture Design. I am now ready to try the principles out in real-life scenarios.  I have the following case. There will be the following things: 3 mixture factors 3 Categorical factors  Most of the recipe is fixed at 83,275% which I will call the BASE - this part will not be changed.So I have used the Mixture Sum function and set that to...

• How to Account for Uncontrolled Factors Using a Definitive Screening Design

  Hi, I am designing a DOE where I will have 6 factors that are controllable, and two factors that are uncontrolled.   When using custom design, I am able to set factors as uncontrolled, however with definitive screening, I cannot.   1.) Is there a way to set uncontrolled factors in definitive screening designs? 2.) If not, how does one account for uncontrolled factors?   Thanks!

• How to design a screening DOE for continuous factors that includes 3 levels (zero, intermediate, high concentration)?

  Hi all, I am trying to design a screening DOE for multiple continuous biological factors for which I suspect a biphasic relationship between the factors and the outcome (= viability): I first expect a positive correlation up until a certain concentration after which I expect a negative correlation due to toxicity at higher concentrations. How can I take this biphasic association into account when ...

• Query on generating DOE with four (2-level) variables and analyzign 2 variables at a time

  Hello: I have 4, 2-level variables and was planning to do a full factorial DOR run without replicate.So 16 runs. Instead of analyzing the result for four variables, what if I analyze only two variables at a time, this will give me total six DOE to analyze within the same set of 16 experiments but each with 4 replicates now.Variables: A, B, C, D instead of analyzing ABCD together, what if I analyze...

• Factors and Response both are categorical

  Hello: What will be the appropriate method of analyzing the significant factors when all of your factors as well as response is categorical. I am working on manufacturing problem of noise where I have four factorsA: Heat applied, levels Yes and No (half of the samples will be heated)B: Water immersion, levels Yes and No (half of the samples will be immersed in water)C: Material, levels Old and New...
