• Finlay Wilkinson Analysis

  I am totally new to JMP and statistics. Can anyone share a learning material about Finlay-Wilkinson Regression and how to execute it in JMP15. We are going to use this in our field crop experiments. Thank you in advance!!

• STATISTIC PROBLEM

  Fit a KNN model to the Titanic Passengers dataset where "Survived" is the response and all other variables (except Name) are the predictor (X) variables. Set the validation to the validation column.  Set the K to 15, and the random seed to 125. Based on the results, what is the optimal K (enter the numerical answer, e.g., 3)   Titanic Passengers" JMP dataset

• k-NN visualization in JMP

  Hi folks, Longtime JMP Pro user here but fairly new to working with the k-Nearest Neighbors classification module.  I'm working with a visible reflectance spectroscopy data set for a geological material classification (two-class) problem.  I have a fairly well-optimized k-NN model at this point with a low misclassification rate on my test set.  So far, so good.  However, I am looking for a way to ...

• Microbial activity and shelf-life estimation

  I realize that this is a little bit off-topic, but still relevant with respect to JMP's degradation/stability platform. I was wondering how to estimate shelf-life from microbiological tests (aerobic plate count for example). Literature and ICH only tell me that "Qualitative attributes and microbiological attributes are not amenable to this kind of statistical analysis" (read " not amenable to line...

• alternative cut-off confusion matrix

  I have used the alternative cut-off probability confusion matrix add-in many times.  Suddenly it is producing nonsensical results on some data sets.  I verified that it still works as expected on an old data set.  Attached is one of the recent data sets in which it does not appear to be working.  The target variable is Stroke and I have a Validation column and a number of prediction model probabil...
