Why Does Categorical Variable Anticipated Coefficient Change Sign?

I am looking for a more detailed explanation of why the Anticipated Coefficient changes sign between subsets of a multi-level categorical factor in the DOE platform. From JMP help: Evaluate Design Options (jmp.com)I understand why factor subsets need to be created for a categorical variable with 3 or more levels, and would expect a table like the following to be going on in the background of the ...

How I can I know if linear model or non-linear regression model fit to my variables?

Hello, I am a beginner user of JMP since I have recently finished the DOE course provided by Coursera. However, I have to use it in my project and so, I am trying to use JMP community forums to find my responses. But, in this case, I could not find the response that I am looking for.I have a 2-level full factorial design with 3 variables and with 2 center points. I considered 2 replicates and ther...

Is a D optimal Design useful in this case?

I have the following problem for which an experimental design has to be created: The stress at a certain point of a model is to be determined by FEA. This model is varied by setting three different parameters. These parameters are to be varied in such a way that the stress is minimized. The stress should be the target value. Angle, modulus and radius are the factors whose influence must be investi...

Kinetics of chemical processes

Hallo,on one side there is an impressing number of possibilies of JMP to plan complex chemical experiments for the study of a reaction and to evaluate the results by nonlinear, multivariate and linear regressions. On the other side, as a chemist, I wonder how or if chemical reactions with an exponential dependence of the temperature according to Arrhenius k = k0 * exp(-EA/ (RT)) or complex reactio...

Simulate A Definitive Screening Design 1000 times.

Hello, I am trying to fit a definitive screening design with a dataset that I already have. I would like to write a JSL script that would fit the design 1000 times. Would anyone be able to tell me how to go about doing this? I have a Y variable of interest, and X1, X2, X3, and X4 as my four x variables. Thanks in advance for your help!

DoE and inputting replicate analytics

Hi, I have performed a DoE as designed, but would like to know how to evaluate replicate analytical data which feeds into the response for each condition. We usually use analytical data provided by our analytical department, but are investigating a rapid analysis tool for future applications. While this tool is helpful, it appears most accurate when performing replicate analysis, and then averagin...

What to do with contained effects

I am running a 2x2 full factorial study and only looking to model main effects and one-way interactions. As shown below, I have a main effect that appears as less significant than the one-way interaction that contains it. I know the interaction factor is also itself insignificant, but in the past I've seen it as significant. In the past i've just removed the insignificant interaction factor before...

Process development with multiple factors

Hi everyone, I'm currently engaged in a process development project with the goal of 1) minimizing the total process time while 2) maintaining or enhancing the yield. This objective is similar to viral vector production case, where maximizing virus yield in the shortest production time is crucial. After consulting with subject matter experts, we've pinpointed 10 factors for potential modification....

Do 3rd order effects help define curvature?

If you have are making a design with a factor you are certain will have a quadratic relationship against a response but you have a wide range, can it be helpful to define a 3rd order model effect for that factor to better identify and model curvature. I work in purification and we often deal with a recovery vs. purity balance. This relationship is usually quadratic around the optimal, where at a l...

Neural networks that learn and predict in real time (incremental learning)

Hello community!!A query:- How JMP is configured to generate neural networks that learn from their inputs in real time (incremental learning) in such a way that it continually updates its weights according to new inputs and generates updated real-time predictions.Greetings,Marco

Which predictive analysis method/column organisation for RSM output with duplicate samples

Hi all. So I'm working on a project where I have 2 x component classes, each of which has 4 items within the class, which are mixed together at varying concentrations over 48 combinations. Figured the best Factor way to do this was to use 2 x Continuous for the max/min concentrations for each class, then 2 x 4-level Categoricals for each of the items. Each of the combinations was made twice, so af...

Could JMP optimize factors with uncertainty?

Hello community!!,A question: will it be possible for the profiler to find the best combinations of factors with uncertainty when performing a simulation, which maximize the total utility and minimize the total cost, generating a table of the best combinations found? For example:
