Variable selection
orsf_vs(object, n_predictor_min = 3, verbose_progress = FALSE)
object |
(orsf_fit) a trained oblique random survival forest (see orsf). |
n_predictor_min |
(integer) the minimum number of predictors allowed |
verbose_progress |
(logical) not implemented yet. Should progress be printed to the console? |
tree_seeds
should be specified in object
so that each successive run
of orsf
will be evaluated in the same out-of-bag samples as the initial
run.
a data.table with four columns:
n_predictors: the number of predictors used
stat_value: the out-of-bag statistic
predictors_included: the names of the predictors included
predictor_dropped: the predictor selected to be dropped
