This model has r nrow(param)
tuning parameters:
param$item
The mtry
parameter is related to the number of predictors. The default is to use all predictors.
r uses_extension("boost_tree", "mboost", "censored regression")
library(censored) boost_tree() %>% set_engine("mboost") %>% set_mode("censored regression") %>% translate()
censored::blackboost_train()
is a wrapper around [mboost::blackboost()] (and other functions) that makes it easier to run this model.
