Webb8.2.1 Potential Scale Reduction ( ^R R ^) In equilibrium, the distribution of samples from chains should be the same regardless of the initial starting values of the chains (Stan Development Team 2016, Sec 28.2). One way to check this is to compare the distributions of multiple chains—in equilibrium they should all have the same mean.
