How to evaluate model accuracy on holdout set

Hello, I am using JMP 13 and I can not seem to find a way to automaticaly evaluate my model's accuracy on the holdout set. I am buliding a linear regression model.So I would like to preserve the model (with the contained effects and estimates sizes), which was bulit on the training set, but calculate accuracy predictors (R^2, R^2 adjusted and RMSE) on the holdout set. In the moment the only soluti...

Discrete?Continuous? Latin Hypercude Design in JMP

Hi all, I have tried Latin Hypercube Design in JMP to reduce a total number of 18 experiments with 2 categorical factors each with 3 and 6 levels. But the software does not allow me to choose any Space Filling Design methods. Is it because LHD is not originally suitable for discrete factors? If so, what methods should I go to build the reduce the number of the experiment?

Logistic regression with multiple outcome variables

I am running logistic regression analyses on a dataset where the outcome has multiple categorical variables. In this case, I am using total number of humans present (continuous variable) to predict the behavior of gibbons (the behaviors are categorical). I am trying to use the parameter estimates to determine which specific behaviors are affected by the number of humans, but I am having trouble ...

K-S Test Interpretation

I am trying to compare regeneration density following wildfires versus unburned areas. I have non-normal data with unequal variances so I ran the K-S Test and got the attached output. I'm not sure which p-value to use. Thank you.

How to Add Profit Matrix to Neural Net Confusion Matrix

Hi all, I'm using a neural net to predict whether or not a customer will prefer to buy retail items at a markdown or if they are likely to buy full-price (i.e., "bargain buyers" vs. traditional shoppers). I'd like to incoporate the opportunity cost of a false positive (giving discounts to what would otherwise be a full-price shopper) using a profit matrix, but changing values on the matrix in the ...

Capability Animation - How to see the LSL/USL Value?

I just discovered this nifty tool called the Capability Animation, where you can play around, dragging the spec limits and mean shifts, and it simulates your capability indices. But, I cannot see the actual LSL/USL values as I drag them! Does anyone know how to make this happen?
