#' The diagnostic, binary-valued variable investigated is whether the
#' patient shows signs of diabetes according to World Health Organization
#' criteria (i.e., if the 2 hour post-load plasma glucose was at least
#' 200 mg/dl at any survey examination or if found during routine medical
#' care). The population lives near Phoenix, Arizona, USA.
#'
#' Results: Their ADAP algorithm makes a real-valued prediction between
#' 0 and 1. This was transformed into a binary decision using a cutoff of
#' 0.448. Using 576 training instances, the sensitivity and specificity
#' of their algorithm was 76% on the remaining 192 instances.
