我需要幫助來查找WINBUGS代碼（第1.4.3節）中的錯誤。WINBugs：數組索引大於數組的上限
在「模型規範」步驟中，模型看起來合理正確。然而，在我試圖加載數據，我得到這個錯誤：
數組索引超過數組上界phi3
可能有人請幫助我更大？我的模型提供瞭如下：
model {
for(w in 1: W){
m[w] <- n[w]-y1[w]
h[w] <- n[w]-y1[w]-y2[w]
y1[w] ~ dbin(delta[w],n[w])
y2[w] ~ dbin(theta[w],m[w])
y3[w] ~ dbin(eta[w],h[w])
y4[w] <- n[w]-y1[w]-y2[w]-y3[w]
logit(delta[w]) <- mu1+theta1[a[w]]+phi1[p[w]]+psi1[c[w]]
logit(theta[w]) <- mu2+theta2[a[w]]+phi2[p[w]]+psi2[c[w]]
logit(eta[w]) <- mu3+theta3[a[w]]+phi3[p[w]]+psi3[c[w]]
