“…Performance of the method is examined in combination with cluster analysis as one of the most widely used methods in the regionalization studies (e.g., Acreman & Sinclair, 1986;Basu & Srinivas, 2014, 2015Burn, 1989;Burn & Goel, 2000;Dodangeh, Soltani, Sarhadi, & Shiau, 2014;Hall & Minns, 1999;Hall, Minns, & Ashrafuzzaman, 2002;Jingyi & Hall, 2004;Kingston, Hannah, Lawler, & McGregor, 2011;Ramachandra Rao & Srinivas, 2006a, 2006bSrinivas, Tripathi, Ramachandra Rao, & Govindaraju, 2008;Toth, 2013;Wiltshire, 1986). Ramachandra Rao and Srinivas (2006b) indicated that some hybrid algorithm can improve results of clustering by combining the strengths of two categories of clustering algorithms, hierarchical and partitional algorithms.…”
