在使用winbugs软件的时候，我要建立泊松模型，编写了以下代码
model
{
for(i in 1:N){
r[i]~dpois(u[i])
u[i]<-alpha0+alpha1*x1[i]+alpha2*x2[i]+alpha3*x3[i]+alpha41*x41[i]+alpha42*x42[i]+alpha43*x43[i]+alpha44*x44[i]+alpha51*x51[i]+alpha52*x52[i]+alpha53*x53[i]+alpha54*x54[i]
}
alpha0~dnorm(0.0,0.001)
alpha1~dnorm(0.0,0.001)
alpha2~dnorm(0.0,0.001)
alpha3~dnorm(0.0,0.001)
alpha41~dnorm(0.0,0.001)
alpha42~dnorm(0.0,0.001)
alpha43~dnorm(0.0,0.001)
alpha44~dnorm(0.0,0.001)
alpha51~dnorm(0.0,0.001)
alpha52~dnorm(0.0,0.001)
alpha53~dnorm(0.0,0.001)
alpha54~dnorm(0.0,0.001)
}
list()
并在list中填写了数据，check model 和load data都没问题，但是当compile时才出现了educational version cannot do this model 这句话，请问这样情况该怎么解决呢？
p.s.初学者，大家帮帮忙哟~
