  • Adding explicit table reference in JSL code leads to unexpected results

    I have a short JSL script that I'm looking to add to a larger automated workflow. The intent is to iterate over the values in a column (layer_type) and if it finds any value other than SSOD the code should return 1. If all values in the columns are 'SSOD' then it should return 0. This is being used in a if/else split in a workflow to throw an error. In general if you have recommendations of a bett...

  • Spectral data + PLS-DA

    Hello everyone! I'm reaching out to see if someone can guide me through the basic steps for performing PLS-DA. Below is an example of the raw data table I'm using in order to construct the classification method. I'm working with spectral FTIR data, and my objective with the classification method is to see if I can classify samples according to the treatment they have received. When I proceed with ...

  • correlation map with categorical and numerical factors

    I have several dataset to analyze. I know how to do a color correlation map with numerical factors in JMP but I do not know how to do a correlation map with categorical and numerical factors. That would be very useful because correlation maps are a compact way to analyze and present a lot of information, especially when there are many factors.  How can I generate a correlation map with categorical...

  • How to constrain asymptotes in 4PL Hill curve fit?

    New user of JMP, running JMP18 and know how to perform basic 4PL fitting. 4PL Fitting is extremely important in many biological assays and we often need to set values of upper or lower asymptote when fitting incomplete IC50 curves with 4PL analysis. Using the 4P Hill fitting equation, is there a way to constrain the asymptotes within graph builder without having to create a custom model? Thank you...

  • Getting the coefficient for main effects in an ordinal variable - least-sq regression

    Hi, I have an ordinal variable (health literacy, with 5 levels). I am testing it against a continuous dependent variable using a least square regression. The output gives me betas for each level of my ordinal, but how do I get the main effect across all levels of ordinal, like SPSS gives you a main coefficient over all levels of the ordinal variable?

  • Scale IDs in Add Graphics Script not working

    I created a script to draw graphs from JSON objects, which works well, but when I tried to overlay one graph on another using two Y axes, I could not get it to work; it always used the left Y axis.  I thought I was doing something wrong, but I finally realized that even the example in the Scripting Guide does not work as it should.  This example is supposed to use the right Y axis, labeled "Test,"...

  • Discovery summit book signings - official list of books?

    Fellow JMP enthusiasts! During the 2024 Manchester Discovery Summit I was surprised to learn that the handing out and signing of books is a tradition. So, I am wondering whether there is a list of the books handed out & signed so far. If it exists, where to find it?I thoroughly enjoyed reading "Bitch" by Lucy Cooke, and I have a feeling "Hello World" by Hannah Frey will be a good read too.
