Error in JAGS code [closed]
I'm trying to run the following code in JAGS
model {
for (i in 1:n){
z[i] ~ dnorm(X[i], tau)
X[i] <- D1*x1[i] + D2*x2[i] + D3*x3[i] + D4*x4[i]
}
denom <- 1 + sum(exp(p))
D1 <- (exp(p[1]))/denom …

I'm trying to fit a lognormal random effects model in JAGS … Below my JAGS code:
# Lognormal Model
# N municipalities
# M years
# W Betas
model {
for(i in 1:N) {
for (j in 1:M) {
k <- (i-1)*8 + j
y[k] ~ dlnorm(mu[k], tau) …

Compilation error in JAGS
JAGS does not accept to have an object receiving multiple values inside different loops. I changed the JAGS code and it worked. … See Below:
JAGS CODE:
model {
for(i in 1:N) {
for (j in 1:M) {
y[(i-1)*8+j] ~ dlnorm(mu[(i-1)*8+j], tau)
mu[(i-1)*8+j] <- beta0 + delta[i] + inprod(x[(i-1)*8+j,], …
