RStan to PyStan Conversion

소개

This skill facilitates the migration of Bayesian inference workflows from R to Python by providing specific guidance on the architectural differences between RStan and PyStan 3.x. While the core Stan modeling language is language-agnostic, the wrapper code for data preparation, sampler configuration, and posterior extraction requires careful translation. This skill offers precise hyperparameter mapping, clarifies the critical transposition of sample shapes, and provides verification strategies to ensure that converted models produce consistent statistical results across both ecosystems.
