If I understand correctly, Random Forest and Boosted tree model in JMPpro using R2 or RMSE as function to judge training/validtion model. If my data (no missing value) want to use minimize Absolute Percent Error min[(pred-true)/true] as function to train the model, how should I do it in JMPpro? or jsl coding? Thank you!
