Hi, I am interested in generating replicates from the posterior predictive distribution of a r.v. X, which has been programmed in WinBUGS using the zeros trick. Can someone suggest whether I am doing it correctly? So, zeros.rep[] in the code below are my replicates. K <- 1000 ll[i] <- ...... ## Log-likelihood of X zeros[i] < - 0 zeros[i] ~ dpois(phi[i]) ## Zeros trick phi[i] <- - ll[i] + K zeros.rep[i] ~ dpois(phi[i]) ## Replicates of y[i] ?
