scorecard_ply can not convert some variables.

[ShichenXie]

could you give me a sample data to reproduce your issue?

If you can use R, please use the r package scorcard, which is much mature.

Hi
Thanks for your response. I have attached the sample data. I am using R and If you perform the following codes you can see the issue.

m = glm( formula, binnedwoe_sample, family = 'binomial')
my_card <- scorecard(bins_var, m, points0 = 600, odds0 = 1/38, pdo = 20)
points_train <- scorecard_ply(binnedwoe_sample, my_card, only_total_score = FALSE, print_step = 0) %>% as.data.frame()

So when you have a look at the points_train you will see that some variables (v1-v7) will have NA values. I still can't figure out why this is the case.
Many thanks

Your sample data and code cant be reproduce, since the 'binnedwoe_sample' is missing. You can provide the data in original values, but not in woe values.

I have attached the original data sample. If you can follow the commands below you can see the the isssue. Many Thanks!

bins_var = woebin(train_data, y="GOODBAD",positive = "BAD|1")
train_binned <- woebin_ply(train_data, bins_var)
names(train_binned) = gsub(pattern = "_woe", replacement = "", x = names(train_binned))
m3 = glm( GOODBAD~., train_binned, family = 'binomial')
my_card <- scorecard(bins_var, m3, points0 = 600, odds0 = 1/38, pdo = 20)
points_train <- scorecard_ply(train_binned, my_card, only_total_score = FALSE, print_step = 0) %>% as.data.frame()

You should use the original data in the scorecard_ply function, but not the woe data frame.

points_train <- scorecard_ply(train_data, my_card, only_total_score = FALSE, print_step = 0)

Since your are using the r version package, please open issue in the r package repo next time.
