【急求解答】请教一个winbugs问题

如图所示，想在原来的logistic函数中增加一个参数lambda，因为极大似然估计太复杂所以考虑用winbugs进行估计，请问我的model写的正确吗？感恩model
   {
    for (i in 1:N) {
    y~dbin(p,1)
   p<-1/pow((exp(-beta0-beta1*x)+1),lambda)
       }
beta1~dnorm(0,1)
beta0~dnorm(0,1)
lambda~dgamma(2,1)
}

list(y=c(1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0),
x=c(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23),
N=23)

#Inits

list(beta1=1,beta0=0,lambda=1)

帮楼主顶一下帖子

This should work.

model
   {
    for (i in 1:N) {
    y[i]~dbin(p[i],1)
   p[i]<-1/pow((exp(-beta0-beta1*x[i])+1),lambda)
       }
beta1~dnorm(0,1)
beta0~dnorm(0,1)
lambda~dgamma(2,1)
}

list(y=c(1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0),
x=c(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23),
N=23)

#Inits

list(beta1=1,beta0=0,lambda=1)
