You can check the code in a presentation I did at PhilaSUG and NJSUG:
Of course monotonicity is not a requirement for credit models or logistic
models. You can transform the data (not WOE) with restricted cubic splines
to model with. Note that you should never bin continuous data in the first
place since you have a number of statistical issues doing that.
Splines, check another presentation:

I am trying to do Logistic Regression (sighs..), I have hundreds of

1) Box Plots of each variable (just box plot not the usual and sometimes un

2) Create Bins automatically of numeric variables so as to see if the target
variable cross tab is increasing or decreasing monotonically.
I saw a link to Optibin Macro that is now in active.
Does anyone have any SAS code for automating the binning process?
