Decision trees: same model inputs, different results

I just repeated a decision tree analysis that I originally did yesterday. The data input and all the modeling options were identical in both runs. However the results differed. I tried it again and got yet a different set of results. Why does this happen? It will be disconcerting to report results that can't be independently replicated.

How to sort/order bivariate JMP charts based on R-value.

I am doing Regression analysis with 1 Y-axis parameter ( dependent variable) & 100s of X-axis parameters(independent variables) and want to see top correlations ( high R-value) at the top. I get all these charts and apply linear fit but by default, these are sorted alphabetically based on parameter name. Is there a way I can sort these charts in order of decreasing R-value?

Using a FOR loop in Formula to create a new column

hi folks, I have a question regarding how I can combine a number of columns created in my table, into a new column that describes whether any of these columns have a specific char value ("screened").Currently my datasets are analyzed with a script that adds "n" new columns that contain the char values "screened" and "unscreened" based on formulas in the script.My goal is to include in the script a...

How to find out where JMP is installed in a windows machine.

Hi JMP Gurus,I'm currently using a Perl script to launch our JSL script. The Perl script looks for the default installation location of JMP in the program files folder. Since there are potentially 4 different versions of JMP running around our workplace, I ended up with the following implementation:1. Attempt to launch the standard version executable of JMP 12 in: C:\Program Files\SAS\JMP\12\jmp.e...

Can you change y-axis scale independently from other y-axis groups

Is there a way to change the y-axis scale for the different y-axis groups independent from one another? As you can see in the graph, the middle group densities are much greater than the other four groups. As a result, it is very difficult to see year to year variations in any of the other groups. I would like to increase the scale for the remaining groups, but keep the middle group at it's current...

Save Residuals to Summary Table Problem

Hi,I have a table with 400k+ rows and in my analysis I have created a summary table.I do a fit Y by X on the summary table and get what I expect. From the pull down I select "Save Residuals" and the new column is not created on the summary data table, but on the original data table. Is this the intended operation? The work around is to separately save the summary data table to break the linkage...

How to classify groups with categorical data?

Hi, Here is an easy one. I have a group of rodent skulls. They are from several named groups which are also geographic regions. One group is classified as "unknown". I have metric data and used Discriminant Analysis and a plot of the Canonical 1 and 2 scores. And, using the values in the Discriminant Scores table to show predictions. I also have categorical data. Briefly, things like the numb...

Calculate between and within subgroup variability using jmp (similar to Minitab)?

Hello,How would I go about calculating between and within subgroup variability using jmp (similar to Minitab)? Note: Group sample sizes are different. I am looking to compare various brands of products tested across different vectors. For example, for each brand there is a given quantity of samples tested per vector. and I would like to compare across brands for that vector, specifically between/w...

JSL to change color of specific cause in Pareto Plot

Hello,I'm trying to change the color of a specific cause in the Pareto Plot using JSL. How can I select a cause by name?For example, I want to implement something like this: cause ({"PASS"}) << Colors (Green);This gives me an error and wants me to use Cause where n is the index of the failure pareto. My issue is that I won't know if my PASS pareto will be #1, #2, etc. Any suggestions? Here is m...

Co-Kriging with JMP and Matlab

Hi!I was wondering if anyone already tried to work with Co-Kriging, using JMP together with Matlab. As JMP only fits Ordinary Kriging Models (Gaussian Process with Gaussian Correlation Function), I would like to send data (generated with Space Filling JMP Platform) from JMP to Matlab, fit the models there (Matlab), and bring the MODELS back to JMP, to use inside Profile Platform. Do you have any e...

Interpreting canonical structure and scores in discriminant analysis

I'm trying to interpret the relative contributions of my variables in a discriminant function analysis of chemical data for three groups of rocks. In a stepwise, linear, common covariance discriminant function analysis I'm able to generate non-overlapping 95% confidence ellipses for my three groups with no incorrectly assigned data points using 6 variables. My understanding is that the scoring c...

Generalized Segmented Distributions

A former classmate of mine from Graduate School has recently published a paper on Generalized Segmented Distributions. Utilizing this method, the distribution can approach any continuous density function of arbitrary form. The method is particularly effective in fitting data with sufficient observations that are skewed and/or multimodal. The paper can be found here:The General Segmented Distrib...
