Version 1.2.0 of NIMBLE released
We’ve released the newest version of NIMBLE on CRAN and on our website. 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). This release provides provides extensive new functionality, including...

nimbleHMC version 0.2.0 released, providing improved HMC performance
nimbleHMC provides Hamiltonian Monte Carlo samplers for use with NIMBLE, in particular NUTS samplers. NIMBLE’s HMC samplers can be flexibly assigned to a subset of model parameters, allowing users to consider various sampling configurations. We’ve released version 0.2.0 of nimbleHMC, which includes a new default NUTS sampler inspired by Stan’...

Version 1.0.1 of NIMBLE released, fixing a bug in version 1.0.0 affecting certain models
We’ve released the newest version of NIMBLE on CRAN and on our website. NIMBLE is a system for building and sharing analysis methods for statistical models, especially for hierarchical models and computationally-intensive methods (such as MCMC and SMC). Version 1.0.1 follows shortly after 1.0.0 and fixes an issue and a bug introduced in version ...

NIMBLE virtual short course, January 4-6, 2023
We’ll be holding a virtual training workshop on NIMBLE, January 4-6, 2023 from 8 am to 1 pm US Pacific (California) time each day. NIMBLE is a system for building and sharing analysis methods for statistical models, especially for hierarchical models and computationally-intensive methods (such as MCMC and SMC). Recently we added support for aut...

Beta version of NIMBLE with automatic differentiation, including HMC sampling and Laplace approximation
We’re excited to announce that NIMBLE now supports automatic differentiation (AD), also known as algorithmic differentiation, in a beta version available on our website. In this beta version, NIMBLE now provides: Hamiltonian Monte Carlo (HMC) sampling for an entire parameter vector or arbitrary subsets of the parameter vector (i.e., combined w...

Version 0.6-8 of NIMBLE released!
We’ve just released the newest version of NIMBLE on CRAN and on our website. Version 0.6-8 has a few new features, and more are on the way in the next few months. New features include: the proper Gaussian CAR (conditional autoregressive) model can now be used in BUGS code as dcar_proper, which behaves similarly to BUGS’ car.proper distributi...
