Question: Does Stan really adjust the MCMC sampling from the posterior distribution internally on a parameter-by-parameter basis? That is, given a parameter vector vector\[2\] theta, does Stan make separate MCMC sampling…

Hi all, The aim of my Stan model is to capture trends in count data over time. It could for example be the number of weekly deaths in a given population. To do so, I used Gaussian processes (GPs) that capture three diff…

Hi, I’ve got a hierarchical model with measurement uncertainties, and I’m running into max treedepth issues. These tend to be accompanied with problems in the split R-hat. There don’t seem to be any other problems (\<10/2…
