  "Description": "An ensemble method for the statistical detection of a rare\nclass in two-class classification problems. The method uses an\nensemble of classifiers where the constituent models of the\nensemble use disjoint subsets (phalanxes) of explanatory\nvariables. We provide an implementation of the\nphalanx-formation algorithm. Please see Tomal et al. (2015)\n<doi:10.1214/14-AOAS778>, Tomal et al. (2016)\n<doi:10.1021/acs.jcim.5b00663>, and Tomal et al.
