DOE with 3 levels for continuous factors

Hi, We would like to do a DOE with 3 continuous factors. 2 of these should have three levels and 1 should have only two. I didn't find a way to specify more than 2 levels for continuous factors in the custom design platform. I could use the center point, but that also adds a third level for the 3rd factor which should only have 2.
A workaround could be to set them up as discrete numercial and set...

DOE without replicate runs not working

Hello,
I encountered a problem when trying to create a custom design without replicate runs.
I have 3 variables, all three are Discrete Numeric with (7,15, and 7) values.
When I enter the Custom design I enter my disallowed combination, model, desired number of runs (30), check that the number of replicated runs = 0 and ask to make design.

The resulting design has replicated runs (in my case it 8 out ...

How to model responses when their sum is equal to 1?

Hello!

I have completed a DoE in order to model the particle size distribution. The distribution is measured by several screens. For each size range (e.g. <1mm, 1-5 mm, >5 mm), I have the proportion of particles, and the sum must be one. My question is how to model the three responses properly, taking into account that the sum of the responses must equal 1. I have included a synthetic table to...

Detection Limit in Definitive Screening Design

I'm running a DSD DOE in JMP18 Pro with 2 categorical factors (Factor A (level A1, A2), Factor B (level B1, B2) and 2 continuous factors (Factor C, Factor D). My goal is to select the better Level in each Factor A, and B (e.g., either A1 or A2, B1 or B2) including any two-way interaction terms for all factors and estimate the quadratic terms in Factor C, D. I chose to add 8 more runs with blocks t...

Evaluate a design build using Easy DOE

We used Easy DOE from JMP 17 to generate a 5 factor/3 response design with 4 continuous (2 level) and 1 categorical (2 level) RSM with 36 runs. Q1: Within the 36 runs there are 3 sets of duplicates. Is this a problem? We assume that since JMP designed it = no, but wanted to check for a better explanation. Q2: Is there a way to perform a "Design Evaluation" of the Easy DOE generated design? In the ...

DOE - blocking augmented design

Hi, I am planning a DOE to save on time/resources, no surprise here. I don’t have much experience with the topic, but would like to push for DOE instead of OFAT within the org I work at, I guess common idea too. About the problem, there are 10 continuous factor, 3 responses. The experiments can be done at 4 labs at physically different locations. Lab 1 has more resources than the other 3, thus the...

When to remove outliers when reducing model?

Hi, When I am reducing a model, I watch the externally studentized residuals to know when outliers are appearing. When should I remove these outliers throughout the model reducing process? If I see no outliers when the model contains all terms, but then I remove a term and an outlier appears, do you remove that outlier immediately and continue reducing, or continue reducing and then remove the...

How do i make one design by combining BBD and CCD in one

How can we include all two polymers, along with their respective factors and levels, in a single design or dataset to compare them effectively and determine which polymer is best suited for this drug?

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 ...
