I add an "region" indicator (has numeric values from 1 to 5) as the varying
intercept in my model (I use "county" data in Minnesota [MN] as my
county-level indicator and interact it with "basement"(bsmt)) and write my
model in Winbugs as:
model{
for (i in 1:n){
y[i] ~ dnorm(y.hat[i], tau.y)
y.hat[i] <- alpha[region[i]] + beta[county[i]]*bsmt[i]
}
for (j in 1:J){
alpha[j] ~ dnorm(mu.alpha[j], tau.alpha)
}
for (k in 1:K){
beta[k] ~ dnorm(mu.beta[k], tau.beta)
}
