How to model responses when their sum is equal to 1?

Hello!

I have completed a DoE in order to model the particle size distribution. The distribution is measured by several screens. For each size range (e.g. <1mm, 1-5 mm, >5 mm), I have the proportion of particles, and the sum must be one. My question is how to model the three responses properly, taking into account that the sum of the responses must equal 1. I have included a synthetic table to...

find is missing start from column X till ncol()

Hi, I have a table that has thousand of columns. I want to use column matrix to find if across a range of columns is missing.

cross validation using k-fold fit quality

I am using Lasso fit with leave one out or K-fold cross validation. Please advise the best way to view the R square and other fit quality metrics (e.g., AIC) in the output. It would be helpful to have this for the training set and the validation set (average of all hold outs).

Life distribution: how to set the markers and weibull fit to use Kaplan-Meier or Turnbull estimates

Hello, The below is the test table I made. According to the description: https://www.jmp.com/support/help/en/18.1/index.shtml#page/jmp/event-plot.shtml#ww1386833 It meas there are total 100 samples. And exactly at 4 readings: 50, 100, 150 and 200, there are 25 new failures happened. So the failure rate I expected will be: 50, 25% 100, 50%, 150, 75% 200,100%. The markers in the Weibull plot ...

Python Code unable to generate output in JSL (JMP 17 Pro)

Hello All, I have a JSL script that creates a Datatable, and I have a python code block within the JSL script which I want to pass the DataTable to make predictions on the DataTable using a trained machine learning model. Before the python code block, the DataTable is accessible and even opens in JMP. However, after the python code block when I try to access the predictions made by the neural ne...

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.

Question About F-Tests in GLMMs with Binomial Errors

Hi,
I have a question regarding Generalized Linear Mixed Models (GLMMs) in JMP pro. Most statisticians consider it inappropriate to use F-tests or t-tests to evaluate predictor contributions in GLMs or GLMMs with binomial errors. This is because F- and t-tests are based on sums of squares, which assume normally distributed residual errors.
While using a logit link function helps linearize the relati...
