Hi, I'm working on some data on heart failure clinics in order to predict death event numbers. I'm relatively new, so I'm confused on some of the concepts on RScript.
I am going to make a Logression model and CART models (decision tree and randomForest), I was wondering on how to find the best split ratio for my data? Or is this number purely arbitrary?
Additionally, should the split ratio remain constant across all three models, or is there an optimum number for each of them?
Thanks in advance
