%description
Implements methods for clustering mixed-type data, specifically
combinations of continuous and nominal data. Special attention is paid to
the often-overlooked problem of equitably balancing the contribution of
the continuous and categorical variables. This package implements KAMILA
clustering, a novel method for clustering mixed-type data in the spirit of
k-means clustering. It does not require dummy coding of variables, and is
efficient enough to scale to rather large data sets. Also implemented is
Modha-Spangler clustering, which uses a brute-force strategy to maximize
the cluster separation simultaneously in the continuous and categorical
variables. For more information, see Foss, Markatou, Ray, & Heching (2016)
