+Posterior keywords
+==================
+
+Below are the definition of some of the keywords used. These are tags added to posterior that we __know__. Hence, there might exist posteriors that should have the keyword where it is currently missing. If you see this, please file an issue and we will fix it. 
+
+```easy```: Posteriors that can be computed with standard Stan settings (adapt delta = 0.8) without any divergent transitions for 10 000 draws and on average use less than 100 leapfrog steps per iteration.
+
+```slow```: Posteriors that take more than 1h to run 1000 iterations/warmup on a standard CPU. The difficulties can be due to different reasons.
+
+```arm book```: Posteriors that can be found in "Gelman, A., & Hill, J. (2006). Data analysis using regression and multilevel/hierarchical models. Cambridge University Press."
+
+```pathfinder paper```: Posteriors used in "Zhang, L., Carpenter, B., Gelman, A., & Vehtari, A. (2022). Pathfinder: Parallel quasi-Newton variational inference. Journal of Machine Learning Research, 23(306), 1-49."

+1. An Rhat (see [Vehtari et al. (2021)](https://doi.org/10.1214/20-BA1221)) below 1.01 for all parameters.
+1. Approximately independent draws, that is, all parameters have an autocorrelation at lag 1 that is less than 0.05 (see, e.g., [Vehtari et al. (2021)](https://doi.org/10.1214/20-BA1221))).

-Computing parameter ESS bounds
-------
-
-The variability of ESS estimate is relatively high, so to assert that we have a reasonable bound on the ESS values, we have simulated the distribution for ESS bulk and ESS tail (see [arXiv](https://arxiv.org/abs/1903.08008)) based on 10 000 normal draws.
-
-We now check that the ESS bulk and tail is roughly within 4 SD from a NULL distribution (that is roughly ```sqrt(7 * S)``` where ```S``` is the total number of draws. This is a rough check for the ESS values, but far from perfect. In the long run, we want to check this with a hierarchical model instead.

-See `ess_bounds()` in ```rpackage/R/utils_reference_posterior.R``` to see details for how bounds are chosen.
