#' Glacier weather data – Sonnblick observatory
#'
#' Weather data from Austria's highest weather station, situated in the Austrian Central Alps on the glaciated mountain
#' "Hoher Sonnblick", standing 3106 meters above sea level.

#' @usage data(weather)
#'
#' @format
#' An array of dimension \eqn{(p,q,n)}, comprising \eqn{n = 136} observations,
#' each represented by a \eqn{p = 5} times \eqn{q = 12} dimensional matrix.
#' Observed parameters are monthly averages of
#' \itemize{
#'   \item{air pressure (AP)}
#'   \item{precipitation (P)}
#'   \item{sunshine hours (SH)}
#'   \item{temperature (T)}
#'   \item{proportion of solid precipitation (SP)}
#' }
#' from 1891 to 2022.

#' DARWIN (Diagnosis AlzheimeR WIth haNdwriting)
#'
#' The DARWIN (Diagnosis AlzheimeR WIth haNdwriting) dataset
#' comprises handwriting samples from 174 individuals.
#' Among them, 89 have been diagnosed with Alzheimer's disease (AD), while the remaining 85 are considered healthy subjects (H).
#' Each participant completed 25 handwriting tasks on paper, and their pen movements were recorded using a graphic tablet.
#' From the raw handwriting data, a set of 18 features was extracted.
