#' Thinned subset of posterior sample from a Bayesian analysis of perception of correlation.
#'
#' Data from Kay and Heer (2016), primarily used for testing and examples.
#'
#' For more details, see Kay and Heer (2016) or the Github repository describing the analysis:
#' <https://github.com/mjskay/ranking-correlation>. The original experiment (but not this analysis of it)
#' is described in Harrison *et al.* (2014).
#'
#' `data("RankCorr")` is a substantially thinned version of the original posterior sample and has omitted several
#' parameters in order for it to be a more manageable size.
#'
#' `data("RankCorr_u_tau")` is used for testing and examples and is roughly the equivalent of the following:
#'
#' ```
#' data("RankCorr")
#' RankCorr_u_tau = tidybayes::spread_draws(RankCorr, u_tau[i]))
#' ```
#'
#' @name RankCorr
#' @aliases RankCorr_u_tau
