What is Stan model?

Stan is a state-of-the-art platform for statistical modeling and high-performance statistical computation. Thousands of users rely on Stan for statistical modeling, data analysis, and prediction in the social, biological, and physical sciences, engineering, and business.

Also, what is a Stan model in R?

Stan is a programming language for specifying statistical models. The Stan code is compiled and run along with the data and outputs a set of posterior simulations of the parameters. Stan interfaces with the most popular data analysis languages, such as R, Python, shell, MATLAB, Julia and Stata.

Beside above, how does a Stan program work? A Stan program defines a probability model. It declares data and (constrained) parameter variables. It defines log posterior (or penalized likelihood). Stan inference: fits model to data and makes predictions.

Beside above, what is Stan tool?

STAN tool is a patented solution capable of assessing the stability of RF & Microwave circuits, which is a critical step in the design flow.

Who uses Stan?

What is Rhat in Stan?

Rhat is a convergence diagnostic which compares parameter estimates across the chains. If the chains have converged and mixed well, then the Rhat value should be near 1. If the chains have not converged to the same value, then the Rhat value will be larger than 1.

How to speed up sampling in rstan?
  1. Try to use vectorize operation, and avoid to use loops.
  2. Remove any not-needed parts to save time, for example, the generated quantities block.
  3. Sampling the chains parallelly, so I simply use cores=4 at the stan(…) code in R studio.

How do I use Rstanarm package?
