scorecard 0.1.9.1

  • fixed a bug is woebin function cant modify positive values

scorecard 0.1.9

  • pdo in scorecard function now suports negative value. If pdo is positive, the larger score means the lower probability to be positive sample. If pdo is negative, the larger score means the higher probability to be positive sample.
  • fixed a bug in woebin function using chimerge method, which is caused by initial breaks have out-range values.
  • added a check function on the length of unique values in string columns, which might cause the binning process slow.
  • fixed a bug in perf_eva function which is caused by the nrow of plot is setted to 0 when the length of plot type is one.
  • the ratio argument in split_df function supports to set ratios for both train and test.
  • If the argument return_rm_reason is TRUE in var_filter function, the info_value, missing_rate and identical_rate are provided in the result.

scorecard 0.1.8

  • remove columns have only one unique values in input dataset
  • modify the default values of x_limits in perf_psi
  • fixed a bug in perf_psi when the label is factor
  • display proc time in woebin
  • fixed a bug in per_eva when estimating AUC
  • fixed a bug in woebin_adj when special_values is provided

scorecard 0.1.7

  • added chimerge method for woebin function
  • special_values option added in woebin function
  • f1 curve added in perf_eva

scorecard 0.1.6

  • Fixed a bug in woebin_adj function when all_var == FALSE and the breaks of all variables are perfect.
  • Provide parallel computation (foreach with parallel backend) in the functions of woebin and woebin_ply.
  • Modified scorecard_ply function.
  • Fixed a bug in woebin when there are empty bins based on provided break points.

scorecard 0.1.5

  • Fixed a bug in scorecard function when calculating the coefficients.
  • Fixed a bug in perf_eva when type="lift".
  • Fixed a bug in functions of woebin and var_filter when removing Date columns.

scorecard 0.1.4

  • perf_eva supports both predicted probability and score.
  • Added the woebin_adj function which can interactively adjust the binning info from woebin.
  • Reviewed woebin function.

scorecard 0.1.3

  • Modified the format of printing message and added condition functions.
  • Added the split_df function which split a dataframe into two.
  • Reorder the binning information. Move the missing to the first binning.

scorecard 0.1.2

  • fixed a bug in var_filter

scorecard 0.1.1

  • Specified some potential problems via conditions
  • Modified examples for most functions

scorecard 0.1.0

  • Initial version
