• 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...

• Control chart: Xbar and S chart with large subgroup size unable to extract or calculate limits

  I am working on building Xbar and S chart to monitor a process where we observe the data (Y) every 1 minute across multiple runs. I wanted a chart where I have the control limits be the average of each time point across runs, which I believe the Xbar and S chart is doing. However, the actual LCL and UCL limits are not showing up, and I don't know how to extract them from the plot (see example char...

• Graph builder removes levels of a variable when adding a local data filter (and I don't want it to)

  I have some categorical data (a Likert scale) with 5 levels, with some responses at each level. When I add a local data filter, one of the levels no longer has any responses, and then this level doesn't show up on the graph anymore, but I want it to (with a bar of size 0). No filter: With filter (notice "Somewhat unhappy" [second level from top] is now missing): I have "Include Missing Categories"...

• Graph Builder: adjust the axes to the filtered data

  If a user applies a data filter to exclude rows, the Graph Builder Plot restricts the axes (and Group X/Y areas) accordingly.
  
                         ... but not always:
  For columns with modeling type multiple response, Jmp (17.1) displays all existing values on the axis (and Group X/Y areas)
  - even if the data is restricted by a global data filter and a local data filter. Is there a setting to change...
