Hello! This question builds on a topic/toy-model that I posted here , where @ricardoV94 helped me a lot. It’s a really simple asymptote function: y \sim N(\mu = \frac{x}{x+k}, \epsilon ) My real data is an ecological distance decay curve. The “noise” around the asymptote function is probably ac…

I played around (a tiny bit) with the code you provided. I can’t even get it run as it is. This seems to be due to the fact that the SD of y_pred is very likely to be \le 0 for some values of xnorm. If you are going to use a linear expression to characterize the scale of a parameter, you might co…

Those posteriors look really neat!

Do you mind if I borrow your toy example for an article I am writing on using log transformations in bayesian models?
