Hi,
   
  I am trying to run a zero inflated poisson model using winBUGS.
   
  I am getting the error:
   
  update error for p[1] algorithm UpdaterSlice.Interval error cannot sample node too many iterations.  
   
   
  I looked in the manual and did a goole search, but I cannot find any reference to this error.  Does anyone know what this means?
   
   
  model{
  for(i in 1:N){
  lambda[i]<-exp(beta[1]+beta[2]*x[i])
  delta[i]<-equals(y[i],0)
  p[i]~dbeta(a,b)
  eta[i]<-p[i]/(1-p[i])
  C<-10000
  logL[i]<-delta[i]*log( eta[i]+exp(-lambda[i]) )+(1-delta[i])*( y[i]*log(lagbda[i])-lamda[i] ) - 
              log(1+eta[i]) - (1-delta[i])*logfact(y[i])
  zeros[i]<-0
  phi[i]<- -logL[i]+C
  zeros[i]~dpois(phi[i])
  }
   
  for(i in 1:2){
  beta[i]~dnorm(0,.001)
  }
   
  )
   
  Thanks,
