Hi, I have the following problem, I would like to use the measurement error operator “me” in a non-linear formula, but it appears not possible as this kind of formula are directly passed to stan:
brm(bf(y ~ b1 * exp( b2 * me(x, x_sd) ), b1 + b2 ~ 1, nl = TRUE),
data = df, prior = …
produces a “no matches for” error
is there a workaround?
