Specifying axial value as rotatable in custom design

Hello,

I am trying to create a custom DOE in order to maximize the response yield of a target quantity as a function of two continuous factors and one 2nd level categorical factor. The interactions of these factors are of the third order, and I am specifying 2 center points. However, I also want to define axial values to set axial positions such that I get a rotatable surface, similar to that of a ...

Problem with adding midpoints to my design (they are not randomly distributed)

Dear Community,
I have created a design with 12 factors, 11 of them are continuous and the last one is discrete numeric with three levels. I decided to add 30 midpoints (see attached screenshot of the experimental design). Why are the factors of the midpoints not randomly distributed?
I tried the model with fewer factors, and the midpoints were randomly distributed as desired.
I also tried increasin...

Weibull model for bacterial decay

I have been asked to do a linear regression using Weibull on jmp. It only seems to work for data with a positive curve (growth), however, when trying to select the Weibull for the decay data it cannot be selected. Is there a parameter I am missing or an assumption that doesn't allow me to use this model?

Multiple Comparison Intervals for Standard Deviation (Test for Equal Variance)

Attached is a sample from Minitab of Multiple comparison intervals for the standard deviation.So, it is a crossed factor test for equal variance.Does jmp have a similar function? Had been trying to do to Fit Y by X but it only separates it.

How to use sample size and power for factorial DoE to determine number of replicated treatments

I'm trying to learn how to operate JMP's dialog boxes for sample size for use in experimental design. I'd like to understand how to determine the number of replicates necessary in a factorial experiment. I'd like to know how many times to run each treatment combination. Assume there is no measurement error, no need for blocking or centerpoints, the response variable is continuous and everything...

Mixture sum

Hi. I tried to make a custom designed mixture experiment with only two different ingredients with varying procents, all other ingredients is helt constant. I tried to use the "mixture sum" option to sum up the two ingredient at the maximum range but it does not work. The last ingredient gets changed into the value stated in mixture sum but that is not what I am after. Any suggestions on what coul...

How to determine term significance based on power value?

Using the design evaluation tool in JMP, I compared a Box-Behnken design with a Custom design (with 28 runs) to evaluate 5 factors with 3 levels each (see below):Given the comparison, the custom design was chosen for the experimental runs. In the evaluation, I found the quadratic terms to be statistically significant (p<0.05) for one or more responses, despite the power for these terms being low a...

Response Screening Effect Size - logistic

Related to the previous post How to get "Effect size" column with Response Screening functionality , I am also wondering how effect size in the response screening platform is calculated, specifically for categorical Y vs continuous X. JMP help shows: "When Y is categorical and X is continuous, the effect size is the square root of the average ChiSquare value for the whole model test." Running b...

DoE with two-choice experiments, continuous response variable

We want to rank the preference of population of animals for n different recipes. Recipes are tested in two-choice assays, where groups of over 100 individuals can choose one choice or the other. Preference for the group is computed as a preference index, a continuous variable that is between -1 and 1. Is there an experimental design that would help reduce the number of combinations to test in ord...

请问JMP有哪些模型可以用于预测股票价格的未来走势？

这是个异想天开的问题: 大家都说股票价格的未来走势预测是艺术、不是科学。
但我还是想看看JMP具体哪里模型能用于这方面。我尝试过使用决策树、随机森林、xgboost。
还使用了DOE制作了均匀试验表来进行分类统计。
虽然这不是一个很好的问题、但还是非常期待专家们的回答。非常感谢！

Sub-sampling data analysis in JMP

In Biology (Plant Sci. and Agriculture) usually we have sub-sampling data for replicates. It's very difficult to analyze these data in commonly use Stat S/W (SPSS/Minitab) because MSS(Error) is calculating wrongly. Without taking averages of samsamples, the easiest S/W for this is using JMP and I need some assistance for this. I've found very useful Youtube video about subsampling in JMP (CRD: S...
