ethet: Functions to Study Etiologic Heterogeneity

#' Simulated subtype data
#'
#' A dataset containing 2000 patients: 1200 cases and 800 controls.
#' There are four subtypes, and both numeric and character subtype labels.
#' The subtypes are formed by cross-classification of two binary disease markers,
#' disease marker 1 and disease marker 2.
#' There are three risk factors, two continuous and one binary. One of the
#' continuous risk factors and the binary risk factor are related to the
#' disease subtypes.
#' There are also 30 continuous tumor markers, 20 of which are related to
#' the subtypes and 10 of which represent noise, which could be used in a
#' clustering analysis.
