The Jenks optimization method, also called the Jenks natural breaks classification method, is a data clustering method designed to determine the best arrangement of values into different classes. This is done by seeking to minimize each class's average deviation from the class mean, while … See more George Frederick Jenks George Frederick Jenks was a 20th-century American cartographer. Graduating with his Ph.D. in agricultural geography from Syracuse University in 1947, Jenks began … See more Jenks’ goal in developing this method was to create a map that was absolutely accurate, in terms of the representation of data's spatial … See more • k-means clustering, a generalization for multivariate data (Jenks natural breaks optimization seems to be one dimensional k-means ). See more The method requires an iterative process. That is, calculations must be repeated using different breaks in the dataset to determine which set of breaks has the smallest in-class variance. The process is started by dividing the ordered data into classes in some … See more Other methods of data classification include Head/tail Breaks, Natural Breaks (without Jenks Optimization), Equal Interval, Quantile, and Standard Deviation.
