Get uncertainty quantification for terminal nodes (only for regression tree)

Description

Get uncertainty quantification for terminal nodes (only for regression tree)

Usage

get_uncertainty_node(
  tree_info_df,
  rf_list,
  test_data_df,
  tree_number,
  node_id,
  dependent_var,
  show_coverage = FALSE,
  show_intervalwidth = FALSE
)

Arguments

tree_info_df	Data frame containing information about the structure of the decision tree, which is built like a "treeInfo()" data frame from the package "ranger"
rf_list	Random forest, which is built like the one you get from ranger()
test_data_df	Data frame of the test data
tree_number	Number of the decision tree of the rf_list to be displayed
node_id	Node ID of the node whose parent ID is to be determined
dependent_var	Name of the dependent variable used to create the forest
show_coverage	Option to display marginal coverage
show_intervalwidth	Option to display interval width uncertainty quantification in terminal nodes (only in combination with show_uncertainty = TRUE)

Value

Character with the number of observations reaching this node
