  • Prediction and confident interval for DOE with random block?

    I have a custom design in the attachment which has 5 continuous factors, one categorical factor with three levels, this design has 36 experiments in 6 blocks due to equipment limit. The results in this file are simulated instead of actual results. I used the default model, and then remove terms which PValue >0.05 one by one in the effect summary, and finally I got a model. However, in the predicti...

  • How to repeat points across extremities in a custom DoE to better understand variance?

    Hi!I am currently optimising an experimental procedure and have opted for a custom design with 4 continuous variables with 2 levels each and a single 3 level-categorical variable. I have included centre points (replicated) to allow for some analysis of variance and the model is generated with RSM interactions not going beyond 2 factor interactions. The residual by plots prove to be very useful but...

  • Script to color cells in a DoE setup

    When creating DoEs, each column is usually a mixture of 2 or 3 different values (high and low values, and sometimes a center value). To better illustrate the DoE setup to myself and my coworkers, I manually color the cells in each column. The high values are colored red, the center values are colored green, and the low values are colored blue. It would be beneficial to automate this coloring proce...

  • How do I reverse the order of contrasts in the Stepwise platform?

    I have a variety of categorical factors that I am trying to fit in the Stepwise platform. For example, "Does the product have a FRAME, LINER, BAFFLE, INSULATION, etc.?"  These are listed in the stepwise menu as Frame{Y-N}, Liner (Y-N), Baffle{N-Y}, Insulation{N-Y}, etc.  Why are some contrasts listed as {Y-N} and others listed as {N-Y}?  This is really slows my analysis down as I build a model bec...

  • About ANOM for variances

    Hi, I'm now studying the ANOM for variances. I don't understand why it needs at least three groups to start the comparison. Does anyone know the reason behind this?  Thank you!

  • Discrete Choice Experiment: None of these options

    Dear community,  Just a quick question considering the formatting of the "No choice" option in JMP 17. If we have Option A, Option B, and Option C, where Option C = none of these options. Do we give three rows of data to JMP? Or would we give two rows of data in binary format, and when both option A = 0 and Option B =0, it will use this information that no option was selected?  In the images below...

  • Change RSM factor levels following DOE run execution

    Hi Community,I created a 16 run RSM (Custom Design) with 1 categorical and 4 continuous factors. Early in the execution I was forced to change several factor levels for practical reasons. I restarted and completed all 16 runs at the new levels, recording on paper all the changes. When I updated the JMP run file and performed Analyze-Fit-Model, the model appeared to retain the previous factor level...

  • Why are my fit models showing different factor significance? In "model 1", Random Block is a Random Effect rather than a Fixed Effect, whereas "model 2" lists all the factors as Fixed Effects.

    When I clicked Fit Model, "model 1" popped up, including "Random Block & Random" as a factor, which means "Random Block" is a Random rather than Fixed Effect. However, When I run "model 2" with just "Random Block" as a factor, everything becomes less efficient. Which is more correct and why? Also, I'm used to the Model 2 output, in which I can click on Scaled Estimates. And I was taught at a JMP t...

  • 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...
