Jenks classification method
WebThis method emphasizes the amount of an attribute value relative to other values. For example, it shows that a shop is part of the group of shops that make up the top one-third of all sales. Quantile. In a quantile classification , each class contains an equal number of features. A quantile classification is well suited to linearly distributed ... WebMar 23, 2015 · The Jenks natural breaks algorithm, just like K-means, assigns data to one of K groups such that the within group distances are minimized. Also just like K-means, one must select K prior to running the algorithm. However, Jenks and K-means are different in how they minimize within group distances.
