• Want to run the same tuning design table for multiple y-variables

  I'm running bootstrap forest as a predicative model. I have hyperparameters I like but want to run multiple times (ex. 500 replicates) to find the random forest that gives me the best validation r square. I have the tuning design table built, but every time it runs for one predicted y-variable (there are 11 in my dataset) I have to manually choose the same design table every time. It's time consum...

• Adding new data using previously develop random forest model

  Community,I am working with my colleague Kim on a project she used random forest to develop a prediction model for plant disease in potato based on soil properties. Here are our questions: How do we use new data with the already generated model that was already validated?How can we validate that the old predictive model is explaining the response variable?The predictive model indicates that with h...

  Hello, I am after a combination of guidance and education. I have recently come across SIMCA as a classification approach. I believe this is not something JMP can address at the moment so my question is, which alternative options can I explore to achieve a similar goal and what would be the advantages/disadvantages when compared to the SIMCA method?  I am currently using JMP 17 Thank you very much...

• How to transform and model non-normal dataset

  Hello, I'm working with a dataset produced from a 5-variable full factorial screening with 3 center points. The raw data is heavily skewed with an exponential distribution. I've tried log, log10, square root and various box-cox transformations and can't seem to get anything even nearly approaching a normal distribution.  ConditionPatterndata11+−−+−0.592−+−−−1.63−−−+−1.784+−++−0.455+−−−−1.376−++−−0...
