Two step-gibbs sampling algorithm vs block gibbs sampling algorithm

What are the difference between two-step gibbs sampling algorithm and block gibbs sampling algorithm, are there any stan examples that can help illustrate their implementation details? Thanks.

Please share your Stan program and accompanying data if possible.

When including Stan code in your post it really helps if you make it as readable as possible by using Stan code chunks (```stan) with clear spacing and indentation. For example, use

model {
  vector[N] mu = alpha + beta * x;
  y ~ normal(mu, sigma); 
}

instead of

model{
vector[N] mu = alpha+beta*x;
y~normal(mu,sigma);
}

To include mathematical notation in your post put LaTeX syntax between two $ symbols, e.g.,
p(\theta | y) \propto p(\theta) p(y | \theta).

Don’t forget to add relevant tags to your topic (top right of this form) for application area and/or class of models you work with.

Hi, @wine_lover. Stan doesn’t use Gibbs sampling, so there aren’t any relevant Stan examples. I don’t know what “two-steps Gibbs” is, but block sampling just lets you sample a bunch of variables jointly in one of the Gibbs steps.
