  • How to analyze impact of responses (e.g. PSD) on product performance in spray drying process in JMP

    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...

  • Correcting Discrete Numeric Factor Level Discrepencies in DOE Model

    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...

  • Space Filling Design - Fast Flexible Filling

    I applied a couple constraints when running a Space Filling DOE and it performed pretty well. However, the algorithm "Fast Flexible Filling" is a bit cryptic. Where can I find documentation that expounds on the algorithm/methods behind "Fast Flexible Filling"?   JMP Ver.18.0.1

  • Design space regions do not match.

    To practice using JMP, I am analyzing and reproducing data from papers. Among these, screening using the Plackett-Burman design and optimization using the central composite design were performed for three impurities to create a predictive model. Similar predictive model equations were created for all of the models described in the paper.   The paper states that pooling was performed during the opt...

  • Predicted values for conversion over 100%.

    Hello everyone, I’m running a Central Composite Rotatable Design (CCRD) in JMP to optimize a chemical reaction, with conversion (%) as my response variable. By definition, conversion should range from 0% to 100%. However, my fitted model sometimes predicts conversion values greater than 100% (and occasionally less than 0%) for certain factor combinations. Here’s what I’ve done so far: My experime...

  • Streamlining Data Workflows With JMP & MATLAB

    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...

  • Sample size for Reliability Life Test

    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?

  • help to get R squared predicted

    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...

  • Sample size calculation for accelerated life testing

    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...

  • How do I replace a prediction expression in a fit model with a specific expression?

    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 ...
