 The score given to a customer is usually a three or four digit integer, and in most cases is proportional to the natural logarithm of the odds (or logit) of the customer becoming "bad".In general, a low score indicates a low quality (a high chance of going "bad") and a high score indicates the opposite.Other scorecard types may include behavioural scorecards - which try to predict the probability of an "existing" account turning "bad"; propensity scorecards - which try to predict the probability that a customer would accept another product if offered one; and collections scorecards - which try to predict a customer's response to different strategies for collecting owed money.
