In order to do so appropriately, one needs a measure to quantify impurity. 5/See5) ■ Gini: Gini(S) = 2pGpB (CART) ■ Chi‐squared analysis (CHAID) with pG (pB) being the proportions of good and bad, respectively. 6, where it can be clearly seen that the entropy (Gini) is minimal when all customers are either good or bad, and maximal in the case of the same number of good and bad customers.
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.

Histograms are a first example. 4 presents an example of a distribution for age whereby the circled areas clearly represent outliers.
A popular example of this is neural networks, which are universal approximators and are high performing, but offer no insight into the underlying patterns in the data.
