• Batch of material - how to treat it in DoE?

  Hello everyone, This is my first post so I hope that my question is not found in other posts. If this is the case please guide me to the relevant post :)I saw in the "Optimal Design of Experiments - A Case Study Approach" book that in Chapter 4 the supplier of raw material, a categorical factor, is treated as a blocking factor for which interactions with the continuous main factors were accounted ...

• How to let JMP give me a calculated (simplified) prediction equation (with coefficients calculated already)?

  When I do a full factorial DOE, and get my model (variables are E and M, y is response).  When I let the model "show prediction expression", it gives me a equation like this:   y=This is a not finished equation, it need you to calculate and simplify it further. I don't know why JMP do this weird things like this since for a statistic software, to give a final simplified equation is not a difficult...

• How is power calculated in optimal designs?

  How is power calculated in optimal designs? I designed a D-optimal split-split plot experiment, and as in classical split-split-plot designs, the power associated with the main plots and subplots are lower than the sub-sub plots, but I struggle to understand if power (and effect size) calculations in optimal designs are computed the same way as classical designs. In other words, how does applying ...

• Mixed Model Trouble

  What is the issue with this data? I can't get any output for the fixed effects tests.I am performing a mixed model of a randomized complete block design. Rep is a random factor while S Rate and N Rate are continuous variables. I would like to see if S Rate or N Rate impact yield. Yield is also a continuous variable.   I can get output when I run it as a standard least squares with the reml method,...

• How to set the response limits using a variable in a JMP script

  Hello, I would like to use a JMP script to automatically set the desirability for a JMP column, based on the statistics of the column itself. I would like to do this because I have multiple metrics and I would like to combine them in a single desirability metric using the JMP profiler platform. I am a JMP 16.1 user.Unfortunately the following code does not work - the response limits are set but th...
