I wish to calculate the weight of evidence of a variable x, which is positively skewed, with over 6000 of the observations are 999 but only 200 range from 1-27. I used the code,
However, no matter what number I used in bins parameter, I can only get 2 bins, [1,27] and [999,999]. Is there any way I can look into the [1,27] closer because they represent a lot? The output from R is shown below,
IV <- create_infotables(data=Test[,-1], y="class", bins=10)
