  • Project saving error - "unable to write to file"

    Hi all - I'm a relatively newer JMP user, not used to writing scripts, and definitely new to working with JMP Projects. That said, I've been mostly successful with creating and maintaining several different project files, in both JMP 16 and 18. However, with one specific project file, I've started getting the following error: "Project could not be saved due to the following error: unable to write ...

  • Testing slices in JMP Pro Mixed Model?

    Hello, I am doing a 4-way, full factorial ANOVA with one repeated measures factor (time, 3 samplings) and three between-subject factors (species, color, and irrigation; 2 levels of each) using the Mixed Model personality in JMP Pro 18.1.0. I'm using the AR(1) repeated covariance structure, as it provides the best fit based on AICc values. The analysis indicates I have no significant 4- or 3-way in...

  • How do I test for unequal variances in mixed model?

    I want to test if the measurement (intermediate) precision from two different labs are different. My data usually consist of the same sample being measured k times per day, across n days in each of the two labs. I analyze the data using Fit Model with lab as fixed effect, and Day as random effect. I would like to compare the total variation (within and between days) between the two labs - somethin...

    My interest is in identifying the strongest predictors of annual per capita growth rate for three groups of bird species: residents, short-distance migrants and long-distance migrants.  My model has per capita growth rate as the dependent variable, and as predictors bird density during the breeding season, and 13 environmental predictors (various measures of climate, food abundance and nest predat...

  • 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.
