Seems rather likely that 999 is not really a measured value but rather
is a missing value indicator.

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
range from 1-27. I used the code,
?IV<-create_infotables(data=Test[,-1],y="class",bins=10)?
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]
closely because they represent a lot? The output from R is shown below,
Table$pdays
pdays N Percent WOE IV
1 [1,27] 243 0.03807584 2.6743166 0.5267751
2 [999,999] 6139 0.96192416 -0.2230081 0.5707022
Thank you very much!!
