Hey all -
I’m working with a mixture model and I want to order the simplex for identifiability. How can I use Stan modeling language to order the simplex?
Should I use
ordered[N] pi and then at each iteration transform
pi back to a simplex? If I do this in
transformed parameters does this happen after each iteration in the sampler?
Is it worth adding this to the math library?
I know people cringe at mixture models…
