Good afternoon, I would like to start a mixture design via the Easy DOE program but I don't succeed to put in in mixture mode. It seems to suggest only screening or response surface designs. Do you know how to set it up in mixture design? Many thanks for your help
Hi, I am reading this paper: Full article: A high-throughput media design approach for high performance mammalian fed-batch cultures where authors mention that they constructed DoE with 16 runs using 43 parameters. If I understood correctly, they basically designed 80 random DoEs, choosing the one that best minimizes the correlations between factors. I was wondering if something similar can be d...
Hi all, I’m working on a DOE with the following factors: 1 categorical variable with 4 levels 2 continuous variables Before running the experiments, I want to know how to evaluate my design to ensure that I can: Confidently identify which variables have the most influence on the response Determine which specific levels of the variables perform better Also, I don’t want to do just the minima...

Hi, I am trying to understand the Color map on Correlations in DoE Evaluation when having categorical factors (like for example: "Solution") with many levels (e.g. "Distilled water", "Tap water", "NaCl"). The Color map on Correlations outputs Solution 1 and Solution 2 in the top label section, but what does this mean? Is Solution 1 the correlation between Distilled water and Tap water (as they a...
I am working on a spray drying process and have used CCD design with D10, D50, and D90 as responses. However, its dissolution profile and its flowability are dependent on the size distribution of the powder (D10, D50, and D90). What is the best way to analyze the effect of the responses (particle size) on the product performance (dissolution and flowability) given that the size distribution values...
Hello to anyone reading this post. I hope you're having a great day! Question Context: I am a junior engineering student and have built DOE with 3 discrete numerical factors at two levels and one response and then conducted trials. Then with JmpPro will use linear regression to develop a model including all interactions for my results. (This is the assignment) However there was an issue during d...
Integrating tools like JMP and MATLAB offers a streamlined approach to engineering analysis, making workflows more efficient and reducing the need for redundant script rewriting. By leveraging JMP’s powerful data analysis and visualization capabilities alongside MATLAB’s robust computational tools, engineers can seamlessly combine the strengths of both platforms. This integration allows for the ra...
I have used the interval explorer for parametric reliability life test planning for sample size calculation of accelerated life test. Please can someone confirm if the sample size returned is the total sample size or sample size per stress levels? Assuming I have 3 temperature levels, do I use 75 samples per temperature level or 25?
Hello!I installed a script from a community response regarding the calculation of R²pred, as shown in the image below (I'm using JMP 18 pro): (link da resposta do @erich_gundlach https://community.jmp.com/t5/JMP-Add-Ins/Predicted-R-square-calculator/ta-p/39927) In PRESS, R²pred didn't appear. (Press is low because I haven't reduced the model yet, don't worry =)) I really need to show these R²pre...
I am trying to use the interval explorer for parametric reliability life test planning tool for sample size required for an ALT test but need some clarification on the following questions. 1. Is the Weibull alpha the characteristic life at stress or at use life? 2. Is the Quantile the pFail at stress or use life and how does the quantile impact the required sample size?3. Is the calculated...
Hi, I am completing a DOE and I have ran a fit model using the JMP software to define a design space based on desirability of certain variables, however one of the desirability variables is a simple ratio of two of the construct model effects, however when running the model, the model is defining its own prediction expression for this variable rather than using the formula in the data table. Does ...
