CHAID algorithm vs. JMP partition (decision tree)
Hi All, I was wondering if anyone could tell me just how similar the JMP decision tree (partition) algorithm is to the classic CHAID approach.Many thanks,Joe Retzer
Find courses, tutorials, and lots of other methods of learning JMP.

Hi everyone,I've tried to search before I asked. I'm learning and very very new with the JMP software, we are using version 10. What I'm trying to do is make a script that will look in any given data table for specific column names and cast the columns into roles for a control graph IR. In the control graph I want it to find the column and use it for the "process" portion. Then use sample labels t...
i have a data set of repeated measures yet the time interval between them is uneven (i.e. 5 min, 15 min, 30min, 60min from impact). when using the MANOVA platform the x axis doesn't allow any modifications. Thought of using the graph builder or the chart platform yet they do not allow labeling unevenly so i would have the indication of the actual times of measurement on the axis.any suggestions?
Hello,
I want to get a column mean into a new column but I want to be able to restrict the date range that I use. I want to be able to say get column mean from day x to day y in my formula. This is the current formula that i have:
New Column ("X",
Numeric,
Continuous,
Format ("Best", 12),
Formula (Col Mean (:WeeklyPercent, :Week, :Source)), Set Selected);
It pull the average weekly perc...
Hi guysI am new to JMP Pro and to its scripting language, as well as to those SAS forums.If you think that I post my question in the wrong place - let me know and please excuse me,My goal is to create a script that will:open CSV filecreate variability chart based on table from this filesave the result as JRP fileNow some details.CSV file might be huge in row number. This file starts with line of c...

i am using graph builder to display continuous data on x and y. if i drag to the top (X group) i get my data in bins (levels as jmp calls them) which is what i want and i can choose how many levels to display but i need to define each level (bin)
right now graph builder chooses the bin and i cannot find how to define manuallyjason
I've been using logistic regression with multiple categorical predictors. I'm particularly interested in the odds ratios, and I understand how the odds ratios themselves are calculated, but I'm having trouble understanding how the test statistics associated with each odds ratio are calculated. JMP gives the disclaimer "Tests and confidence intervals on odds ratios are likelihood ratio based." M...
Hello,I was wondering if there is a way to export a prediction equation from JMP to Excel?Thank you,Konrad
Is there a method to quickly design your own profiler. For example, if I already have a complex model (formula) with several independent variables, can I set up my own profiler to see the impacts of individual independent variables?

In Europe, we found it common to use Cpkn as a non-normal Cpk metric, where mean was replaced with median, and stdev was replaced with IQR/1.35. For some "regulatory" or "customer" reports, this seems to be accepted rather than the usual "torture the data until it says its normal" approach with transformations. Does anyone have similar experience or better ideas? (Note: any use of capabilit...
Hello,I am trying to use jsl to remove the x-axis variable and replace it with a different one. It looks like I should use the GraphBuilderBox <- Remove Variable() tool, but since I change the x-axis variable multiple times, I do not know its name and would like to use the Remove Variable(Role("X"), Position(1)) method, but this does not work. Any assistance would be appreciated.Thank you,Martin
How would I calculate the shape of the average (using the median) of a variable from a group within a data set? I need a certain function for calculating the centre of gravity (centroid) or Euclidian centre of this group of variable.
Many thanks!!
Hi everybody,I would want to calculate LD50 and LT50 from a dataset organized in 6 columns:- Name of the compound (I just got 1 compound named A)- Concentration of the compound (2 dilutions per compound)- Individual number (a fixed number of 10 individuals is used per assay)- State of the individual at the end of the experiment (1 = alive, 0 = dead)- Day death (experiment last 15 days)- Experiment...
