matlab中实现openbugs或winbugs的功能调用

model {
  beta[1:p] ~ dmnorm(mu[], precMat[,])
  #for (j in 1:p) {
  #  beta[j] ~ dnorm(mu[j], precMat[j,j])
  # }
  for (i in 1:n) {

    #http://www.math.helsinki.fi/openbugs/data/Docu/Tips%20and%20Troubleshooting.html
    # suggest replacing  probit(p[i]) <- delta[i] with p[i] <- phi(delta[i])
    pr[i] <- phi(s[i]) 

    y[i] ~ dbern(pr[i])
  }
