Table 7 Leave-one-out cross-validation k-NN error rates for scale normalized data. Error rate and rank of each scale normalization method. "Rank" is described in detail in Table 5. For a given data set, the smallest error rate(s) and rank(s) are shown in bold. The methods and data sets are described in Tables 3 and 4, respectively.
