In tomasgreif/woe: Tools to calculate Weight of Evidence (WoE) and Information Value.

Description

This function calculates information value for numeric vectors. This is done using decision tree.

Usage

  iv.num(df, x, y, verbose = FALSE, rcontrol = NULL)

Arguments

df	data frame with at least two columns
x	column (numeric) for which Information Value should be calculated
y	column (integer/factor) with binary outcome. It is suggested that y is factor with two levels "bad" and "good" If there are no levels good/bad than the following assumptions are applied - if y is integer, than 0=good and 1=bad. If y is factor than level 2 is assumed to mean bad and 1 good.
verbose	Prints additional details when TRUE. Useful mainly for debugging.
rcontrol	Additional parameters used for rpart tree generation. Use ?rpart.control() to get more details.

Examples

iv.num(german_data,"duration","gb")
