getIV will compute the given binning IV of x variable, return a numeric.

Usage

getIV(df, cutbound, totalgood = NULL, totalbad = NULL)

Arguments

df	A dataframe only with two variables, X and Y.
cutbound	A single value for factor variable, or a vector with lbound and ubound for numeric variable.
totalgood	Default NULL. if not default, will use them directly, otherwise will recalculate based on df.
totalbad	Default NULL. if not default, will use them directly, otherwise will recalculate based on df.

Value
