Fisher's exact or Chi Square?

Hello
I want to know which is more accurate and should be used to invistigate the association between two categorical variables: Fisher's exact or Chi Square? The sample size is more than 300 and the table is 3*3. The good news is that: fisher's exact test is now available for this type of tables (more than2&2) in JMP pro 18

Is there an equivalent to multicollinearity for categorical variables in JMP?

I'm trying to create a predictive regression model to predict the value of a continuous variable. Not that multicollinearity matters all that much to me since I'm purely looking for prediction, but I have a large number of categorical variables (20+) recorded (along w/ 20+ continuous variables), & I'm looking to do feature selection/variable reduction so as not to over-fit the data, & was wonderi...

Assessing for colinearity for categorical variables and/or binary outcome

I am seeking to assess for colinearity among categorical variables to be included in a multi variable nominal logistic regression. I understand that VIF is useful for this, but I’m unable to find VIF for categorical variables or a binary outcome. Other methods have been less initiative like a LASSO. Is there a way to, either with or without LASSO, to evaluate for colinearity? Thanks!

Practical Implementation of FDE Results

This is not a specific question regarding how to use FDE, or how to interpret any of its output, more so a question around implementing it in a practical way and what that workflow looks like. JMPs documentation on the FDE platform suggests that the 2 main ways to use FDE is for exploratory analysis (so in a manufacturing context let's call that process monitoring through the FPC control charts)...

Test post-hoc Kruskal Wallis

Hello,
I'm running a Kruskal Wallis test on JMP. I want to observe whether the score obtained in paragraph comprehension differs between 3 groups. The samples are small and unpaired: a group of 5, a group of 5, and a group of 11.
The Kruskal-Wallis test is significant. I want to carry out post-hoc tests to see which group differs from the central tendency.
Is the Wilcoxon pairwise test appropriate? I...

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...
