However, if a regression model were to be used (which is typically more common because of its interpretability), then since it can only fit a line, it will miss out on the nonmonotonicity. By categorizing the variable into ranges, part of the nonmonotonicity can be taken into account in the regression. Hence, categorization of continuous variables can be useful to model nonlinear effects into linear models.
However, outliers can be hidden in unidimensional views of the data. Multivariate outliers are observations that are outlying in multiple dimensions. 3 gives an example of two outlying observations considering both the dimensions of income and age. Two important steps in dealing with outliers are detection and treatment. A first obvious check for outliers is to calculate the minimum and maximum values for each of the data elements. 3 Multivariate Outliers tools can be used to detect outliers. Histograms are a first example.
Choosing the optimal time window for the sample involves a trade‐off between lots of data (and hence a more robust analytical model) and recent data (which may be more representative). The sample should also be taken from an average business period to get a picture of the target population that is as accurate as possible. It speaks for itself that sampling bias should be avoided as much as possible. However, this is not always straightforward. Let’s take the example of credit scoring. Assume one wants to build an application scorecard to score mortgage applications.
