Hello! So i am trying to implement a certain model written in BUGS into PyMC3. The OpenBUGS code goes something like this: model{ lambdac ~ dgamma(ac,bc) lambdav ~ dgamma(av,bv) sc ~ dnorm(expsc, tausc) sv ~ dnorm(expsv, tausv) tausc <- 1/(nv*varsc) tausv <- 1/(nv*varsv) expsc <- nc*(1- (1-ex…

Figured it out myself. Not to mention there is a typo at the end of s_c line, where it should be lambda_c, sv and sc are observed random variables so I needed to pass the observed values 2214 to sv and 2222 to sc. That solves all of it
