  • Process Capability: Subgrouping vs. no subgrouping?

    Hi, I am currently working on a Cpk Ppk analysis (JMP Pro 17.1) and I am very unclear on what subgrouping is and whether it is needed in my analysis. I have the same lab results dataset however did the Process Screening/Capability slightly differently:

    1. Process Screening --> Process Variables = Grade A (leaving Grouping, Subgroup, Time and By column empty).

    Result: 2. Process Screening --> Process...

  • Caution: Places where Jmp does something unexpected

    Definitely, JMP is Not a Spreadsheet . And that's great!! Besides this difference, there are other places where Jmp doesn't do/behave/produce what a newbie / innocent Jmp user expects.
    If a user knows these issues and the remedies and workarounds -  he/she can
    a) save a lot of time b) be safe from data loss c) be sure that the results are as expected.

  • Capability from a bivariate regression

    Hi I read this post by Phil Kay, and it helped we some of the way towards my goal: https://community.jmp.com/t5/Discussions/Tolerance-Interval-for-Regression/m-p/302845 Would it also be possible to calculate an expected capability from a bivariate regression, if I have a lower and upper spec limit? Example: I have data measured for and Response(Y) at several different temperature levels (X) and I ...

  • Randome sampling from a lognormal distribution shape

    Hi all, 
    I have a distribution lognormal with bellow shape/scale parameter (made by 165 data) Now I want to randome sampling with different sample size (5pcs, 10pcs...) What I want is I expect when running more data it will still follow this distribution shape. 
    So I want to simulate what kind of data I will receive when sampling 5/ 10/20 samples in different times. I expect each time will show abit...

  • How to estimate the ideal sample size to validate failure rate in a process?

    Hello!I have a factory process with a hypothesized failure rate of p=0.02, based on previous trials.I would like to get the ideal sample size to validate if my process has a failure rate no larger than 0.02. How would you approach this? Thanks in advance :)

  • JMP 17 Fit Y by X Points NOT jittered

    Since I have updated from JMP 16 to JMP 17 my variability charts have started behaving differently. Making the points jittered in JMP 17 look more like violin plots than jittered. This is frustrating since the new charts look ugly IMO. Does anyone know if this was an intended change or this is some sort of bug?Cheers.

  • How to prove that the composition of the chemical mixture before and after treatment is significantly different?

    Hello! I need to show that compositions of chemical mixture before and after treatment are significantly different. Composition is given in weight %, so the total of all components' weight % in the mixture is 100%. This also means that if one component weight % in the mixture decreased after treatment all other component weight % should be increased. Can I use "Test Mean" from the Distribution pla...
