EWMA platform improvementsWhat inspired this wish list request? I have been using the EWMA platform more recently and believe these improvements will make the user experience more efficient and less frustrating.
What is the improvement you would like to see?
- Add stages option like control chart builder
- Allow local data filter and column switcher to work
- Shift lines
- Have different colors for up shift and down shifts lines
- Have ability to have the shifts work like CUSUM vs just when the trend line cross the mean/target line
- Have platform ignore excluded rows as a red arrow drop down menu item
- Make it so the chart size doesn’t reset when you change a setting
- Have an option to show UCL and LCL values on the EWMA chart (use constant limit numbers)
- Have an option to show UCL and LCL values on I-MR/X bar chart
- Add ability to have a “head start” EWMA(-1) value
- This will allow if you have rolling data for the trend line to not keep restarting at the target value and thus changing the nature of the control chart
- Add in being able to save limits in a tall table format
- Add in an ARL profiler that’s would have ARL(0) and ARL (Delta) be optimized for values of Lambda and K sigma
- Add K Sigma to the parameter platform vs being buried in the red drop down menu items
Why is this idea important? This will remove inefficiencies in the platform and allow more capabilities for the end user.
Quality and Process EngineeringRe: EWMA platform improvements - Status changed to: Needs InfoHi @shampton82 are you using the new EWMA Control Chart platform under Control Chart?

Re: EWMA platform improvementsHey @mia_stephens !
Yes I was using the new EWMA platform in JMP 18.0 on Windows. I didn't think these were available but if you could let me know which ones you think are I can review them.

Re: EWMA platform improvements - Status changed to: AcknowledgedOK, thanks for the confirmation @shampton82 . It does appear that most of these would be new features.
Development is currently working on improvements to charts under the Control Chart menu. It would be helpful if you could help prioritize these items. Can you identify the 3-5 items on the list that are most important to you?
Re: EWMA platform improvementsSounds good @mia_stephens
Top ones:
- Allow local data filter and column switcher to work
- Shift lines
- Have different colors for up shift and down shifts lines
- Have ability to have the shifts work like CUSUM vs just when the trend line cross the mean/target line
- Make it so the chart size doesn’t reset when you change a setting
- Add in an ARL profiler that’s would have ARL(0) and ARL (Delta) be optimized for values of Lambda and K sigma
- Add K Sigma to the parameter platform vs being buried in the red drop down menu items
Thanks!

Re: EWMA platform improvementsThanks @shampton82, do you have a top 1 or 2 most important requests?
Re: EWMA platform improvementsHey @mia_stephens
Final down select would be there:
- Make it so the chart size doesn’t reset when you change a setting
- Add in an ARL profiler that’s would have ARL(0) and an ARL (Delta) that could optimize both for values of Lambda and K sigma (this is similar to the CUSUM request as well so hopefully by doing one you will be most of the way there for both)
Thanks!

Re: EWMA platform improvementsI went to create a new entry for adding Local Data Filter and Column Switcher options for both EWMA and CUSUM charts but am glad I found this first. My assumption is since it works for the Multivariate control charts, it will work here as well. I can't think of another platform I use regularly that does not have these features.
I think this is the right place for this request as @shampton82 has added many other good suggestions here. I hope they make their way into the next Early Adopter @mia_stephens!
Re: EWMA platform improvementsThanks @jszarka , we hear you!
