STANDARDIZING DATA Standardizing data is a data preprocessing activity targeted at scaling variables to a similar range. Consider, for example, two variables: gender (coded as 0/1) and income (ranging between $0 and $1 million). When building logistic regression models using both information elements, the coefficient for income might become very small.
When building a sample, one can then only make use of those that were accepted, which clearly implies a bias. 1 Unfortunately, all of these procedures make assumptions and none of them works perfectly. One of the most popular solutions is bureau‐ based inference, whereby a sample of past customers is given to the credit bureau to determine their target label (good or bad payer). When thinking even closer about the target population for credit scoring, another forgotten subset are the withdrawals.
