woebin_ply bug

[GISH123]

When applying woebin into a dataframe, there is a occasional bug that happens if:

1. that feature has missing value;
2. in woebin, you make a bin with special value = 0

Example:

This feature will be ok applying on a dataframe, since it has no special value

!However, the following two feature:

If the to-be-applied dataframe has value 0, it will be given woe = -0.841608( [-inf,0.1) bin ) which is false
should be 0.529374 instead.

I kind of quick fixed by trying to force where my original data value = 0, I give it the true woe value(0.529374) instead.

Summary in traditional chinese:
簡單來說就是如果該dataframe，該特徵有missing value且在woebin有設定special value = 0，則所有0會被給予下一個(bin)分箱的值

I know the woebin_adj function is not so stable. I'll fix it if I have time in the future.
You can try to use the R version package which is much mature.

Well, at least outside of this particular problem, the woebin_adj work wonders.
Quickfixing it doesn't take much time too.
Thank you for your reply.
