• What technique do I use to justify eliminating measurements at a specific timepoint in a series?

  I have measurements of an attribute at initial, 2hr, 4hr, 6hr. I want to drop the 4hr measurements because it does not add much value to the business application.  The measurements exhibit a negative slope from initial to final... What technique or rationale might I use to justify eliminating the 4hr measurement? [I was thinking along the lines of Information Gain, but I admit I don't know much ab...

• How to pull discreet numbers from "smoother" fit from scatter chart

  Hello, I am plotting a series of different devices and their signal response responses as a function of time. I wish to pull from each smoother plot the time value once the plot crosses a value, say 3100. The scatter data is too coarse to get the time at which this occurs however if there is a function behind the smoother fit for each device then this information should be available.  Does anyone ...

• DOE Question - Too Few Degrees of Freedom

  I am very new to the JMP community - just got my account up and running the other day.  I am running an experiment and I wish to see the effects of the main factors and all two-level interactions. I am using an L27 Taguchi array to account for four 3-level factors with three responses per row/per trial. I left some columns blank to make room for the two-level interactions. However, what I don't un...

• Questions regarding Response Surface Methodology (Box-Behnken design matrix)

  Good morning,  I am currently trying to optimize some enzymatic reactions using Response Surface Methodology, in concrete, Box-Behnken design matrix. Using the program, you choose your independent variables or factors (pH, temperature, enzyme load, etc) and assign a "low" and "high" value to each. The program then automatically calculates the "middle" value.  My first question is if it is possible...

• How do I Use Boolean Logic on Continuous Factor to Create a DoE

  Hello. Thank you in advance for your time to consider this problem. I am trying to create a DoE with 2 continuous factors and a 2-Level discrete numeric factor.I want to create a DoE in which if the discrete numeric factor value is 1, only range of values from the 1st continuous factor is experimented. And, if the discrete numeric factor value is 2, only range of values from the 2nd continuous fac...
