get_bins_table_all {creditmodel}

Table of Binning

Description

get_bins_table is used to generates summary information of varaibles. get_bins_table_all can generates bins table for all specified independent variables.

Usage

get_bins_table_all(
  dat,
  x_list = NULL,
  target = NULL,
  pos_flag = NULL,
  dat_test = NULL,
  ex_cols = NULL,
  breaks_list = NULL,
  parallel = FALSE,
  note = FALSE,
  bins_total = TRUE,
  save_data = FALSE,
  file_name = NULL,
  dir_path = tempdir()
)

get_bins_table(
  dat,
  x,
  target = NULL,
  pos_flag = NULL,
  dat_test = NULL,
  breaks = NULL,
  breaks_list = NULL,
  bins_total = TRUE,
  note = FALSE
)
