Thanks for using the package!
Unfortunately rstanemax
doesn't have a functionality to use proportional error model.
I would suggest the followings as potential alternatives - each with own drawbacks but hopefully good enough approximation for most cases.
Thank you author. Your answer is of great help to me and it have solved my problem.
Dear author,
Thank you for developing this great package, which is very convenient to build the Emax model. However, it seems only the addtive residual error can be estimated by the function
stan_emax
? I'm wondering whether the following proptional residual error can be estimated:$$y = (e0 + \frac{e{max}\times x}{ec_{50}+x})\times (1+\varepsilon) $$
where $$\varepsilon \sim N(0, \sigma^2)$$
Many thanks to your help.
Best regards, Min
