Many regressions: unique (stable) function for exponential and s-shape behaviour

That was really only for situations where you need to have group-wise intercepts but need to make them block orthogonal to the other parameters in the likelihood. Similar idea to

Stan for Bayesian Hierarchical Models

Hi All, A paper, essentially on using Stan for non-linear/non-Gaussian hierarchical models, is now online at: https://arxiv.org/abs/1806.02068 The paper is very much in draft form, and any suggestions and comments are very much welcomed. The paper aims to overcome problems with applying (Euclidian metric) HMC to hierarchical models. The methodology is easily implemented in Stan, and produces potentially large speedups / improved robustness for such models. The idea is to introduce an explic…

but I don’t know that it is going to fix this thread.
