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.

Details

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]))
