Odds ratios for multiway tables

On twitter earlier today, someone asked if the Cochran-Mantel-Haenszel (CMH) odds ratio (OR) test was available in JMP when the stratification variable is not the X in Fit Y by X. Anytime I need to go from two variables to more than two variables, the first place I look is Fit Model. The beauty of fit model is that not only can I use as many variables as I want, but I can consider interactions bet...

Bivariate Histogram

Can JMP create a bivariate histogram of 2 data columns from a data set? I am thinking of something that creates graphs similar to those one can make in Matlab using the "hist3" command?http://www.mathworks.com/help/stats/hist3.html(see bottom figure in this link as an example of what I'm visualizing)I don't necessarily need the fancy aspect viewpoint like shown in the figures from the Mathworks we...

Is there an inverse to the Day Of Year() function?

I have a day of year column, and need to convert it to a date. I've wracked my brain over this. There's probably a simple solution but it escapes me.

Show as graph reference lines

I'm importing spec limits with a script to every datatable that I want to graph. While distributions show specs, box plots do not. I've been trying to insert the "Show Spec Limits(1) in multiple areas, but with no success. I am a JSL noob, so looking for some expertise. Going through each column properties GUI to check the box is unmanageable. Here is a snippet of code;dt = open("datatable.jm...

Weights and frequencies in logistic regression

I came across this situation where the logistic regression outcome is identical when using weights or frequencies. I find it surprising since this would not be the case for linear regression at all. Weights and frequencies have different meaning as in this link: http://blogs.sas.com/content/iml/2013/09/13/frequencies-vs-weights-in-regression.html Does anyone know the reason for the identical outco...

How to find ETA squared effect size for MANOVA?

Hello, Does anyone know how to calculate the eta squared value from a manova analysis in JMP? I know that the E and H matrices tab shows the sum of squares for each parameter, but which values do I use to calculate SStotal and SSeffect? In my model, I have 2 control variables (age and gender) and then a two way factorial. If only one of these variables (in addition to both control variables) is si...

help!! How can I change each variables plotted points to something other than solid circle in graph builder?

help!! How can I change each variables plotted points to something other than solid circle in graph builder, such as an open circle or diamond? Attached is an example of an older graph (created in older JMP version) with the variables points marked differently and an example from newest JMP version.

loop for and if for column name change

all,I would like to rename column name depending on some condition using a for loop with a if conditional.But doesn't work.If I set up the function out of the for loop then no issue.code as belowFor( i = 1, i <= 100, i++, If(i > 0 , Column(i) << set name( char(munger(Column name(i), 1, "::try::", "-" ) ) ) ););

Is there an easy way to get the FWHM (full width half max) of a curve using JMP?

Dear JMP community,Is there an easy way to get the FWHM (full width half max) of a spectral curve using JMP? Finding the minima and maxima are fairly straightforward, but then calculating the FWHM seems to be much more laborious in JMP, especially if the data is sparse and we would like to interpolate to get more accurate intersections between the peak and the FWHM value. In my case, the peak is o...

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...
