How do you write a column formula which can group by rows defined by another column?

Hi, I would like to be able to write column formulae which can perform various column formula functions within groups defined by rows in, for example, a column called 'group'. There are various mentions of the 'group by' button when using gemini, but I cannot find this. For example, I would like to calculate the first cycle in the below table when the retention first passes 60 % (cycle where re...

Script for combining data table scripts with data from multiple files and saving into on JSL file

Hey everyone! Okay after trying for way to long I am stuck on how to get this code to work. I am trying to make a script that will allow a user to select from a list of open files, and for each file selected the code will copy the data table scripts and then paste them all into a single JSL file that I can then run at a later time and will open all the data tables again. Basically like a way to ...

Nelson / Westgard Rules available on P charts, but not. Laney P' charts

Hi - I have noticed that in Control Chart Builder, JMP 18.2.1, if I create a P chart, JMP provides options for warnings for a number of different Nelson & Westgard rules. However, if I switch to Laney P', only "Test Beyond Limits" is an option. I'm curious if someone can explain the reasons why ... software bug? Good statistical reason those tests aren't applicable for a Laney P' chart? Some...

XGboost training, validation and testing

Here's my current approach: I'm using 10-fold cross-validation for model training and validationI keep a separate test dataset completely excluded during this training phase (hide and exclude in the table before launching the model)After training, I manually generate predictions on this test dataset (save predicted to table and I un...

Simulate vs Bootstrap methods in JMP: which to use when and why

Hi All, I'm hoping someone from JMP might be able to provide an explanation as the the differences/similarities of the Simulate vs Bootstrap approaches when evaluating model estimates. (JMP Pro) Some links to previous Discovery Summit presentations from Gotwalt and others can be found here, here, and here. One clear difference between the methods is that Simulate requires you to swap out a col...

Modification de valeurs numériques

Bonjour, j'ai exporté une table excel qui fini en table de données avec des colonne sous forme caractère. Or dans ces colonnes les valeurs sont numérique entre 0 et 5000. Mon problème est que sous forme caractère les valeurs supérieures à 999 sont écrites comme ça (1 000). Et quand je modifie la colonne en numérique toutes les valeurs supérieures à 999 disparaissent. Comment puis-je faire pour que...

STATS on recurrence analysis, loglinear NHPP model

Hi, I am new to recurrence analysis and JMP.
I did the analysis and use loglinear NHPP model. I have a little trouble understanding the results (in attached image). It seems that the γ and δ values are listed in the Effect Marginals section of the result. If I want to do stats on gamma compared between two groups (AlphaC and Sym 1.0). How do I do that? JMP is not generating a p value so I want to d...

permutation test for PLS-DA

Hi all! I've run a PLS-DA test for a data set that consists of FTIR spectral data of 5 different systems under 5 different treatments. I've used the fit model platform so that I could handle categorical variables in my Y variables. According to PRESS statistics, this model has an optimum number of factors of 7 and possesses good discriminating power between my samples. Then, I noticed that the st...

How to assign columns to 'Cause' and 'Grouping' roles, 'scale' and 'shape' effect in JMP recurrence analysis

Hi, all
I am a new member to the community. I am assigned a task to perform recurrence analysis on our data. I never used JMP or did any recurrence analysis. So I will bring some stupid questions for sure.
The data we have are robots repair. We want to see repairs event pattern for the bots and I was told to use recurrence analysis (don't know why). So we have around 15000 robots, I used the 'bot_id...

Customer quantile

Hello, looking for the upper and lower cut off of exponential distribution and Weibull distribution, I could find custom quantile to designate the probability. Have a couple questions. In the old jump version, saw it quantile feature allowing probability number to type, it is the same as custom quantile in JUMP 17. Seems like there is confidence level set as default value of 0.95, having trie...

May I ask a question: Regarding the "Model Sensitivity Profiler" in "Constant Stress ALT Design". The pre-estimated values have been set in the "Acceleration Model settings", and these set values cannot be modified. Besides, the values of "Approx. Fail Time for Setting 1" and "Approx. Fail Time for Setting 2" in the "Model Sensitivity Profiler" are also unchangeable. What is the significance of th...
