Stan

Stan is a statistical software platform designed for Bayesian data analysis, enabling researchers to build complex models and perform advanced statistical inference. It uses a language called Stan modeling language to specify models, then applies algorithms like Markov Chain Monte Carlo (MCMC) to estimate the parameters based on data. Stan is valued for its flexibility, efficiency, and ability to handle intricate models with uncertainty quantification, making it popular among statisticians and data scientists for rigorous, reproducible statistical analysis.
