I’m learning abou Stan and started watching videos on internet. But all of my tries failed, because of this same error:

Error in compileCode(f, code, language = language, verbose = verbose) :

Thanks !!!

This worked for my model, but I have a sample problem including a “generated quantity”.
The message “Stan model ‘third_model’ does not contain samples” show.

generated quantities {
  vector[n_new] y_new;
  for (t in 1:n_new){
    y_new[t]=normal_rng(l[t-1]+b[t-1], sigma);
  }
}

Is there more to the message than just “Stan model ‘third_model’ does not contain samples”? It’s hard to tell from just that if there’s an issue with the model or an issue with the installation.
