#' Parkinson's disease speech classification data set
#'
#' @details From the UCI ML archive, the description is "The data used in this
#'  study were gathered from 188 patients with PD (107 men and 81 women) with
#'  ages ranging from 33 to 87 (65.1 p/m 10.9) at the Department of Neurology
#'  in Cerrahpaşa Faculty of Medicine, Istanbul University. The control group
#'  consists of 64 healthy individuals (23 men and 41 women) with ages varying
#'  between 41 and 82 (61.1 p/m 8.9). During the data collection process,
#'  the microphone is set to 44.1 KHz and following the physician's examination,
#'  the sustained phonation of the vowel `/a/` was collected from each subject
#'  with three repetitions."
#'
#'  The data here are averaged over the replicates.
