cforest and cforest_unbiased for testing and training datasets
...ed # of samples in my testing dataset? The resulting analysis will be applied to my specified testing dataset to assess misclassification and accuracy. I am aware that the options of cforest_unbiased do not allow allow the fraction value to be altered so my second question is is data.controls <- cforest_control(teststat = "quad", testtype = "Univ", replace = FALSE, ntree=2000, mtry=2, fraction=.99) the equivalent to data.controls <- cforest_unbiased(ntree=2000, mtry=2) except I have eliminated the default testing dataset?
