• How to (or can I) use prediction profiler for setting specification limits and test yield enhancement?

  I have a data set with columns of mean, median, sigma, LSL (lower spec limit), USL (upper spec limit), Cp, Cpk and Parameter Yield Loss [%] for 10 measured parameters for parts (~5000 identically built parts, part IDs are rows). Some parameter Cpks are below 1.33 (may or may not have low Cp). It appears from initial data analysis that the limits are not correctly set. Using the prediction profiler...

• Nominal logistic fit effects summary and zero p-vaues

  In the effect summary of the logistic fit, I expected to see a logworth value for a p-value that appears to be zero. But 3 out of 4 parameters with p-values of zero did not have a logworth value. So I check the p-value with the scientific notation format and the 3 parameters without a log worth value were actual zero not a very small number close to zero.  The RSquare (U) for this model is 1. I'm ...

• Deconvolution mass spectra

  I am a JMP 17 Pro user and I am pretty sure what I want to do is pretty straightforward but I'm just not quite getting there. The problem is explained in the attached powerpoint where the figures help clarify the problem I am trying to solve. In this analysis, a single mass peak is obtained by scanning a voltage to deflect a beam of ions of specific mass through a slit into a detector that measure...
