Recent versions of NIMBLE now include the ability to use macros in models. NIMBLE is a system for building and sharing analysis methods for statistical models, especially for hierarchical models and computationally-intensive methods (such as MCMC, Laplace approximation, and SMC). A NIMBLE macro is a succinct syntax that expands to ...
