  • Missing Data and SVM

    I have started using the Support Vector Machines platform but it appears that predictions are missing for observations that are missing a continuous factor.  There is no informative missing setting for SVM, but the prediction formula shows that missing nominal data is used in the formula.  However, when a continuous factor is missing, then the prediction is missing (and the prediction formula does...

  • Why am I getting no K-fold validation for my linear regression? It only shows "."

    Doing a linear regression, and both in stepwise and in the final model output it only shows "." under K-fold cross-validation? Why? I recall seeing a K-fold # for my previous model, though I don't remember the exact section or screen.

  • Calculating effect size

    I have a data set of about 2000 patients. There are two groups one with the critical illness and others with known critical illness.I have done a univariate comparison between the two groups based on a there are age (continuous variable) and a number of other categorical variables like sex or race comorbidities et cetera.Because of the relatively large dataset most of the differences come back as ...

  • 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 ...

  • 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...

  • What does it mean when the solution path for Elastic Net is not single-valued?

    Dear JMP Community,   (W10, 64-bit, JMP Pro 15.2.1)   I am running a model to assess the active predictors. I am doing this by using the Autovalidation add-in to generate a Null Factor for my data. I then use the GenReg platform to find estimates for each possible X-factor and then Bootstrap those estimates to get a better assessment of the contributions to the response. I came across a very stran...
