2.0.3 vs 4.0+ stacking results differ
Probably a general and naive question, but I recently used caretEnsemble (both caretList and caretStack functions) for a classification analysis with the new version 4.0.1, but when comparing the results obtained with the same script with version 2.0.3, I noticed a dramatic decrease in classification performance. How can I reproduce the same result with the newer version of caretEnsemble?
