• JMP stability test report not showing both specification limits

  HelloI have a response with two sided specification limits entered as Spec Limits in Column Properties, and tick mark in "Show as Graph Reference Lines". When I make a Reliability and Survival->Degradation->Stability analysis, I get an earliest crossing time of 13.99, were USL is crossed. However, USL is not shown in the overlay plot - only LSL is shown.I would like to see both specification limit...

• Microbial activity and shelf-life estimation

  I realize that this is a little bit off-topic, but still relevant with respect to JMP's degradation/stability platform. I was wondering how to estimate shelf-life from microbiological tests (aerobic plate count for example). Literature and ICH only tell me that "Qualitative attributes and microbiological attributes are not amenable to this kind of statistical analysis" (read " not amenable to line...

• how do I introduce a custom three parameter life distribution into JMP Analyze-->Reliability and Survival--> Life Distribution

  want to be able to perform standard set of life distribution analyses on a custom three parameter life distribution ... how do I configure platform to have an additional life distribution to show up along with standard list of Weibull, Exponential, Lognormal, DS Weibull, etc the CDF for this life distribution is given by F(t|p,a,y) = 1 - exp(p*exp(-t/a)-yt-p) or expressed equivalently F(t|a,y,x) =...

• Determination of product specs by Stability Results

  I would ask an help for the following problem.
  I got data from a stability study of my product.
  By using the tool Reliability and survivor> Degradation I got a prediction of the expiration date based on the spec that I have now.
  In order to extend this expiration data I cuould need to change the spec.
  For example
  -my product spec say: not less than 100 Pa
  -I have product in stability that at time 0 have...

• When forcing intercept to zero, why JMP does not provide R-squared?

  Hello, I have some questions.  When I have a linear model in JMP, I want to force intercept to zero.So, In Fit Special,  I chose "Constrain Intercept to 0" then I got the new output from JMP. My questions are1) why JMP does not provide R-squared when intercept becomes zero? 2) R-squared is calculated by SSR/SST, can I calculate R-squared by myself using the data JMP provides? If I calculated by my...
