  • parameterisation options in ANOVA

    So how do you set the parameterisation used in the ANOVA model for categorical variables - i.e. say you have a variable that has 2 levels, JMP will report the parameter estaimte for one of them and the other is assumed to have coefficient of zero. Other software I use allows you to choose which one is set to zero, i.e. first or last. Or instead set the sum of the coefficients to zero so you get a ...

  • How to test if a treatment yields twice the response of a reference?

    I have a dataset with a control treatment, a reference treatment, and an experimental treatment. The question I want to answer is if the experimental treatments gives twice the response of the reference treatment after correcting both for the control. I tried using a 'custom test' with the statement 'experimental - 2 * reference + control = 0' [reworked from 'experimental - control = 2*(reference ...

  • Shift Analysis for Large Number of Tests

    I’m trying to check for run-to-run variation across a large number of tests — e.g. >1,000 tests The data is in long format, with all test values in a single column (TestValues). Each unit has measurements across multiple runs (e.g., WW1, WW2, WW3), identified by a WW column, and we have a UnitID to track which unit it is. I want to: Check if there’s a statistically significant shift across runs f...

  • Normalize across trials using controls

    I have a datasets of populations with a response. I triplicated the experiment, so I have 3 trials of data, but the response rate likely varies between trials. It is a hypoxia response rate, which is sensitive to things like humidity/temperature that I can't perfectly control.    Each trial consists of a population with different treatments, plus empty vector controls.    So like this, but with li...

  • blocking in jmp

    hi, i have a question about blocking in DoE. should we always follow the blocking option that JMP suggest with each design?? or can we do it our way?? for example. i am looking to do Box-Behenken design which has no blocking option at all but i was thinking of (doing all 13 run) in one day as the experiment is very short. then reopeat this over three to five dys and use day as a block were the in ...

  • permutation test for PLS-DA

    Hi all!  I've run a PLS-DA test for a data set that consists of FTIR spectral data of 5 different systems under 5 different treatments. I've used the fit model platform so that I could handle categorical variables in my Y variables. According to PRESS statistics, this model has an optimum number of factors of 7 and possesses good discriminating power between my samples. Then, I noticed that the st...

  • Rows inclusion in PCA

    Hello,   I am running a PCA on an NMR dataset that contains some missing values. This isn't due to an error—it's simply the nature of the data, as some samples do not show certain peaks.  I have noticed that when I include these parameters Y variables in the PCA and color the score plot by sample, some samples are missing entirely from the plot. It's not consistent—some samples with missing values...

  • 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...
