# R/LocomotorPerfor.R In QBAsyDist: Asymmetric Distributions and Quantile Estimation

#' Data on locomotor performance in small and large terrestrial mammals.
#'
#' A detailed description of these data is available in Iriarte-Diaz (2002). This dataset is also used in  Gijbels et al. (2019c).
#' For \eqn{n = 142} species of mammals measurements on their body length, body mass
#' (in kg) and maximum relative running speed were recorded. The maximum relative
#' running speed measurement takes into account the body length of the mammals, and
#' was obtained by dividing the maximum speed of the mammal species by its body
#' length.
