• Initialize data - very useful - but fragile!

  Hi, the initialize data settings in the column menu are quite useful.
  Who managed to control the settings via JSL?
  
  In the scripting index, I just found:which fits to "constant" mode. How can I set the other modes?

• Question about R2 for weighted linear regression in JMP

  I used JMP to conduct a weighted linear regression analysis. However, RSquare value of the regression output by JMP (around 0.76) doesn't match my own calculation using the general formula of R2 = 1 - SS_residual/SS_total (around 0.78). The regression parameters output by JMP match my own calculation, so I suppose the regression was conducted correctly. I was wondering if R2 output by JMP is incor...

• Optimising Concentration of Two Factors

  Hi all,I am trying to develop a screening platform to find the best mixture of two factors. I have chemical A and B and want to run experiments with a variety of concentrations of just A, just B, and then a variety of experiments with A and B mixed together in different ratios. I have previously only performed two-factor DoE and am confused about where to start with this experiment. I initially th...

• Does the partition platform require equal variance?

  I have highly right skewed data (see distribution Leaks/mi Yr attached), only about 400 leaks on ~4,000,000 segments of pipe. I use the partition platform to identify factors for our model with differences in leak rates. But my data indicates unequal variance (attached RefService2023wLeaks - FitY by X, fails 4 of 5 variance tests). Does the partition platform require equal variance? By the Central...

• Manually amending a DoE experiment suggested by JMP

  If for whatever reason, it is not possible to run a particular run, but a related one is possible, can the DoE design be manually amended? For example, if experiment ++-++ is suggested but is not possible and ++--+ is (and the latter does not appear elsewhere in the original design) can the user manually make the substitution, whilst bearing in mind that this change will likely alter the significa...
