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]))Kay, Matthew, and Jeffrey Heer. (2016). "Beyond Weber's law: A second look at ranking visualizations of correlation." IEEE transactions on visualization and computer graphics 22(1): 469-478. doi: 10.1109/TVCG.2015.2467671
