  replace_blank_na = TRUE, var_kp = NULL)

Arguments

dt	A data frame, which is the original dataset for training model.
card	A data frame or a list of data frames. It's the scorecard generated from the function scorecard.
only_total_score	Logical, Defaults to TRUE. If it is TRUE, then the output includes only total credit score; Otherwise, if it is FALSE, the output includes both total and each variable's credit score.

# load germancredit data
data("germancredit")
# filter variable via missing rate, iv, identical value rate
dtvf = var_filter(germancredit, "creditability")
# split into train and test
dtlst = split_df(dtvf, y = 'creditability')
# binning
bins = woebin(dtlst$train, "creditability")
# scorecard
card = scorecard2(bins=bins, dt=dtlst$train, y='creditability')

# credit score
# Example I # only total score
score1 = scorecard_ply(germancredit, card)

# Example II # credit score for both total and each variable
score2 = scorecard_ply(germancredit, card, only_total_score = FALSE)
