  • Problems with Reproducibility

    I teach using JMP and I became aware of some reproducibility problems in the following cases:   1) My students who use different operating systems like windows and MacOS get different results from models that require randomization like NN even if they use the same random seed like 123. This problem is frustrating because assignments that use a random seed for reproducibility reasons are supposed t...

  • 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 ...

  • Random data from a factor table without using Fast Flexible Filling Design

    Hello!
    Is there an easy way to make random data from a factor table (the thing used to define factors in the DoE platform) without using Fast Flexible Filling Design? Fast Flexible Filling Design starts to become very slow after 1,000 runs.
    I would really appreciate any suggestions.
    Best wishes,

  • Which experimental design is most appropriate when one of the factors is hard to change?

    Hello everyone,    I'm relatively new to DoE. Currently, I’m planning to run a screening design for 8 continuous factors, one of which is hard to change due to technical constraints.   Initially, I considered using a Definitive Screening Design (DSD) with a sorted run order. However, I’ve realized that this approach may not be appropriate when a split-plot structure is required.   Given this limit...

  • Predicted values for conversion over 100%.

    Hello everyone, I’m running a Central Composite Rotatable Design (CCRD) in JMP to optimize a chemical reaction, with conversion (%) as my response variable. By definition, conversion should range from 0% to 100%. However, my fitted model sometimes predicts conversion values greater than 100% (and occasionally less than 0%) for certain factor combinations. Here’s what I’ve done so far: My experime...

  • Help with Multiple Linear Regression

    Hi everyone,
    I'm a bachelor chemistry student, and I have a task where I need to create a formula using multiple linear regression in JMP to predict the concentration of the distillate.

    I already have the dataset, which includes many independent variables, such as:
    Temperature
    Reflux ratio
    Reflux flow rate (debiet)
    Pressure in the tower
    …and more
    The dependent variable I want to predict is the concentrati...

    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...
