Stan is a probabilistic programming language for Statistical inference written in C++.[1] The Stan language is used to specify a (Bayesian) statistical model with an imperative program calculating the log probability density function.[1]:2
Stan is licensed under the New BSD License. Stan is named in honour of Stanislaw Ulam, pioneer of the Monte Carlo method.[1]:xii
Contents
Interfaces
Stan can be accessed through several interfaces:
- CmdStan - command-line executable for the shell
- RStan - integration with the R software environment
- PyStan - integration with the Python programming language
- MatlabStan - integration with the MATLAB numerical computing environment
- Stan.jl - integration with the Julia programming language
- StataStan - integration with Stata
Algorithms
Stan implements gradient-based Markov chain Monte Carlo (MCMC) algorithms for Bayesian inference, stochastic, gradient-based Variational Bayesian methods for approximate Bayesian inference, and gradient-based optimization for penalized maximum likelihood estimation.
- MCMC algorithms:
- No-U-Turn sampler[1]:3, 26[2]:28 (NUTS), a variant of HMC and Stan's default MCMC engine
- Hamiltonian Monte Carlo
- Variational inference algorithms:
- Black-box Variational Inference[3]
- Optimization algorithms:
- Limited-memory BFGS (Stan's default optimization algorithm)
- BFGS
- Laplace's method for classical standard error estimates and approximate Bayesian posteriors
Automatic differentiation
Stan implements reverse-mode automatic differentiation to calculate gradients of the model, which is required by HMC, NUTS, L-BFGS, BFGS, and variational inference.[1]:199 The automatic differentiation within Stan can be used outside of the probabilistic programming language.
Usage
Stan is used in fields including social science[4] and pharmaceutical statistics.[5]
